Hello,

i need to keep a bunch of CompiledMethods in WeakSet, but i am a bit afraid, that it wont work as i want to, because of CompiledMethod>>= implementation, because a code, which i currently writing doesn't changing a method's bytecode, but changing its trailer instead, and so, this could lead to undesirable effects..

If i could have a WeakIdentitySet...

We can add it to 4.2.

Meanwhile, i think i have nothing else, but just use a degenerate WeakIdentityKeyDictionary , with methods in keys and nils in values. :(

Hi Christoph,

You can probably come up with a general method that creates a Set wrapper around any kind of Dictionary, like Java has it: https://docs.oracle.com/javase/8/docs/api/java/util/Collections.html#newSetF...

Kind regards, Jakob

Could we add it to 6.1? :-) I always use a WeakIdentityKeyDictionary or another weak dictionary as a replacement and it feels like a workaround ... At least, GNU Smalltalk and Pharo seem to have implemented that. :-)

Best, Christoph
