A development environment that lets you edit your language as you edit your program in that language.
The language is defined with a grammar that you can edit. That grammar is simultaneously used to parse your program. You can also define bells and whistles like syntax highlighting in the grammar.
Has it already been done? Wait, I already know the answer, so I'll change the question: Where can I download it?
fuck off with your lex/yacc/flex/bison comments because that's clearly not what I'm suggesting
