I've suggested before (http://lambda-the-ultimate.org/node/1354#comment-15935)
that Dasher should be able to be hacked into something that is extremely
effective for code. Simply using the BNF as generating (rather than "matching")
the syntax should make it extremely effective and should be rather easy to add
to Dasher. Adding things like type-based disambiguation, smart identifier
lookup and other such features from normal typing IDEs would be more involved
but increase throughput even more. I can see such an interface approaching or
even possibly exceeding the speed of typing code.
