[plt-scheme] Re: On C#

Yeah -- one of the standard complaints. :)

Completing the methods of a class is tricky, since you don't have a
type system to tell you what the pool of methods is.

You can do completion based on the keywords in, say, the hdindex and
keywords files you find in the documentation directories. That's
probably the easiest approximation.

Good luck with your research!
