I see two problems with this:
1. #World asClass does not return a class.
#classNamed: can solve this.
2. We are trying to remove all direct references to the Smalltalk
namespace, this however hardcodes the Smalltalk namespace again.
self environment can solve this.

why not let #asClass raise an error and make another one like
Symbol>>asClassIfAbsent: aBlock
^Smalltalk globals at: self ifAbsent: aBlock.
?

now after some thinking. I'm wondering why this is good addition or the

I do not know... thinking aloud.
sounds cool :)
VAST has an #asClass method on Symbol that does more or less this:
Symbol >> #asClass
^ Smalltalk at: self
What about this?
^Smalltalk at: self ifAbsent: nil
^Smalltalk globals at: self ifAbsent: nil
So one could also write:
#MyClass asClass ifNotNil: [ :myClass | ... ]
