autoEnclose is not Smalltalk-specific. In all languages, including
plain English, when you use an opening parenthesis, 9 times out of 10,
there's gonna be a closing one, so autoEnclose is convenient pretty
much everywhere. The exceptions are a tiny minority. Nevertheless,
these are independently adjustable preferences which you can turn off
if it doesn't suit you and they won't bother you even in

-1. I need autoEnclose for all my writing, not just Smalltalk code.

Applications which want to prevent users from being able to access
Smalltalk can and should be able to do that, however, just as
spreadsheet cells accept formulas, in a Smalltalk environment the
default should be the one that accepts Smalltalk expressions. With
Syntax Highlighting off, it's virtually the same as a basic
text-editor for anyone who doesn't know Smalltalk-ability is there.
