the only think is that the #() and '' will not be created all the time but in the compile method literal frame. Stef
would the idea to be to rewrite every #() with Array empty?
If that was the case could you get the compiler to do that as an optimization? I quite like the fact that #() is the empty array. it's nice and compact; quite aesthetic.
cheers, Mike

- Added Array class>>#empty and String class>>#empty to provide applications with canonicalized instances of these oft-used objects; since they are embedded as literals in the CompiledMethod.
