Hello,<br>
<br>
i currently tried to implement a proxy (subclass of ProtoObject) with<br>
own IfTrue:/ifFalse: methods.<br>
What i can't understand, is why VM throws me with #mustBeBoolean<br>
message instead of doing real send if optimized pattern fails (when<br>
receiver of #IfTrue: is a non-boolean)?<br>
<br>
Is there any way, without modifying compiler, how to force it to do real send?<br>
<font color="#888888"><br></font></blockquote><div><br>Oh, you'll also have trouble with >>class and >>==. These two messages are implemented directly in the VM and bypass method lookup. I have no solution to this but there's a patch for the VM here: <a href="http://wiki.squeak.org/squeak/2074">http://wiki.squeak.org/squeak/2074</a>.<br>
