Yes, I'd guess that you are triggering the !! delimited reading when you
give a .st. In short, giving a .st file as an argument triggers a FileIn
operation, not an execute smalltalk script.
It just happens that FileIn is an executable format (sort of), so you can
use it as a script engine until you reach such issues.
