Re: [Pharo-dev] Collect on IdentitySet

Hey All,

The collect: on IdentitySet returns Set. Is this really wanted behaviour or is it a bug?

There was a long discussion about this http://forum.world.st/IdentitySet-collect-tp4792384.html and I thought this was fixed issue 14535

For example:

set := IdentitySet with: 'foo' with: 'bar'. newSet := set collect: [:e | #size -> e size ].

This two assertions do not pass: self assert: newSet size == 2. self assert: newSet class == IdentitySet

Surprisingly (for me), if I change the implementation of collect: to use self species new instead of: Set new, the Pharo becomes really unresponsive...

Cheers, Jan
