Dear List,
This morning, Jannik and I were surprised by the class RuntimeStorage.
RuntimeStorage>>initialize: capacity
byGroup := Dictionary new: 24.
byName := IdentityDictionary new: 10000.
elements := OrderedCollection new: capacity
Why byName reference an identify dictionary? Why not a dictionary?
Names are usually accessed through their name as a String apparently
(e.g., importing Smalltalk packages keys entities with a String).
Should entities be accessed through a symbol instead of a string?
If entities are stored in an identity dictionary, then names must be
accessed with a symbol. If entities are to be accessed with a string,
then a dictionary should be used instead of an identitydictionary.
Cheers,
Alexandre

In VW, we use Symbols for names and not strings. One reason is exactly
that identity is faster than equality.

This is what I though. There is something wrong in the Pharo Smalltalk
importer then.
It should be hard to fix.

I hope you meant that it should _not_ be hard to fix :)
