However, I do not understand the reason why this restriction is used when other similar jumps (break, return) can be &quot;conditional&quot;.<br />

				I think the whole idea of these restrictions was that there should be a linear path from the start of a block to the next reception statement to still allow the unfolding of the interleave to an alt-statement.<br />
<br />
If-statements that include goto statements don't fit into that. In my opinion, goto statements that do not jump out of the interleave also don't really fit into that.<br />
<br />
Additionally, if statements are not treated by this clause, though similar constructs are allowed if they don't contain reception statements. <br />
<br />
const boolean E := C; while (E) { S1; break } while (not E) { S2; break; } <br />
<br />
is equlivalent to <br />
<br />
if (C) { S1 } else { S2 }<br />
<br />
So, allowing if-statements that contain no reception statements should also be considered.			</td>
