<br />
We could introduce the type 'any' to be used for external function in-parameters.<br />
<br />
This would allow, for instance, to declare and implement such a function as valueof() as an external function<br />
<br />
external function valueof(template any t) return boolean;<br />
<br />
Typical use-cases are normalization, stringification/logging, runtime-checking, special encoding functions.</td></tr><tr class="print"><td class="print-category">Steps To Reproduce</td><td class="print" colspan="5"></td></tr><tr class="print"><td class="print-category">Additional Information</td><td class="print" colspan="5">If such a feature existed, some of the predefined functions in the standard could be pushed into a UsefulFunctions library (which could still be standardized) so that they are not further cluttering up the global name space.</td></tr><tr class="print"><td class="print-category">Tags</td><td class="print" colspan="5">No tags attached.</td></tr><tr class="print"><td class="print-category">Relationships</td><td class="print" colspan="5"><table border="0" width="100%" cellpadding="0" cellspacing="1"><tr><td class="print"><span class="nowrap">related to</span>&#160;</td><td class="print">0007867</td><td class="print">closed&#160;</td><td class="print"><span class="nowrap"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=127">Gyorgy Rethy</a></span>&#160;</td><td class="print">the ispresent, ischosen, isvalue, isbound predefined functions should be moved to operations.&#160;</td></tr></table></td></tr><tr class="print"><td class="print-category">Attached Files</td><td class="print" colspan="5"><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR7455-1.docx (240,526) <span class="italic">26-08-2019 14:27</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3853&amp;type=bug<br /><img src="http://oldforge.etsi.org/mantis/images/fileicons/doc.gif" alt="docx" />&#160;CR7455-2.docx (216,731) <span class="italic">26-08-2019 15:11</span><br />http://oldforge.etsi.org/mantis/file_download.php?file_id=3857&amp;type=bug</td></tr><tr><td class="print-spacer" colspan="6"><hr size="1" /></td></tr><tr><td class="form-title">Issue History</td></tr><tr class="print-category"><td class="row-category-history">Date Modified</td><td class="row-category-history">Username</td><td class="row-category-history">Field</td><td class="row-category-history">Change</td></tr><tr class="print"><td class="print">19-07-2016 15:02</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=508">Jacob Wieland - Spirent</a></td><td class="print">New Issue</td><td class="print"></td></tr><tr class="print"><td class="print">15-08-2016 11:54</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=82">Jens Grabowski</a></td><td class="print">Note Added: 0014071</td><td class="print"></td></tr><tr class="print"><td class="print">15-08-2016 11:54</td><td class="print"><a href="http://oldforge.etsi.org/mantis/view_user_page.php?id=82">Jens Grabowski</a></td><td class="print">Assigned To</td><td class="print"> =&gt;

&quot;Values of open type occurring on the right hand side of an assignment are compatible with a value “a” of a type “A”, if the actual value contained in the open type value is compatible with “A”.&quot;<br />

				The reason for that sentence is the possibility of formal out parameters of type any (where the actual parameter is semantically on the left hand side of the formal parameter) and inout formal parameters of type any (where the actual parameter is both on the left and the right hand side). <br />
<br />
The sentence means, for instance, that if a variable of type A is given to decvalue then it should be assigned something compatible with A if decvalue has decoded successfully. Thus, even the external functions need to respect such type restrictions and cannot assign something of an incompatible type.			</td>
