The issue I could not solve on my own is this: I would like to instantiate from symbols. My use-case is a collection of class names which I want to ask to return one instance each.

Such that: #Foo asClass new -> a Foo whereas asClass is the method I am looking for.

(self environment at: #Foo) new -> a Foo

Or if you want it to only resolve Symbols which are actually classes: self environment classNamed: #Foo Example: self environment at: #Transcript -> a TreadSafeTranscript self environment classNamed: #Transcript -> nil Also, if not found, classNamed: returns nil, while at: raises an error.
