<br />
would give the same result;  isbound shall be used in both cases anyway, if there is a possibility that x.f may be uninitialized and may be skipped otherwise. In the above case the the whole contsruct for the x.f==omit syntax is more complicated and it could strengthen the frequent misunderstanding that omit is a value (what omit is *not*).<br />
<br />
For templates we are introducing a more generic matching checking mechanism, while this syntax would relate to the particular omit case only (but, what it should return for ispresent?)<br />
<br />
So, I think, this would be just a syntactical sugar of limited usability, and hence I don't support it.			</td>

				what about template parameters which may be omit? fields are not the only things you want to check for omit and using the istemplatekind function for this seems heavy-handed to me.<br />
<br />
Basically, at the moment I would use a workaround by defining record with an optional field and declaring a constant where that field is omit and then use that field for comparison.<br />
<br />
If such a workaround is available, why not allow it directly, I wonder. It might be of &quot;limited usability&quot; but for those who like the usability, it would be much nicer than such nasty workarounds. I don't see the harm in the feature, either.			</td>
