[Pharo-dev] Collect on IdentitySet

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