[plt-scheme] Re: On C#

I'm guessing that the most helpful completions will be when methods
from the mred GUI classes are completed, so we want some approximation
to the truth that includes them.

My (long-standing, never implemented) thought is to look at the front
of the file for `require' lines, then somehow map those to some
(cached) version of their exports and maybe method names too.

Perhaps this is something I should be extracting from the documentation.
