As soon as you would display the code for many methods in a single text pane,
you will find file-based-educated people making large refactorings in
a single pass...
Imagine this leads to many syntax errors, they will soon be willing to
save their changes for a later rework...
This would be a complete change in programming flow and if we really
want to support this, we would have to:
- add a way to save syntactically incorrect code
- let IDE tools work on partially correct code (syntax highlighting,
IMHO, these features add a lot of complexity... Is it really worth?
I like the discipline of focusing on a single method until it is at
least syntactically correct.
On the other hand, in Smalltalk we have to transfer the complexity of
multi-method changes in the refactoring engines/menus when some simple
modify/replace in a file would work.
