Welcome!
Traditionally, one would do this:
(Smalltalk at: #String) new
Smalltalk here is not a class, but a global variable whose value is a
SystemDictionary mapping class names to class objects.
Pharo is working towards less dependency on globals like these, so the new way
would be like this:
(self environment at: #String) new
(Where environment essentially does 'Smalltalk globals'),
