[antlr-interest] Re: ACE C preprocessor by Gosling

[Matthew Ford]

My two bits worth are (mainly to do with user interface)
11) No dialog boxes that ask you "Do you really want to do that", even for
deletes and overwrites of files.  These should be replaced with unlimited
undo (persistent would be nice).
11a) As a corollary of 11) no  "File Save"  menu item as any changes you
make should be always be saved (Hay that's why you made them wasn't it).
