Agreed.  Getting the Typesript d.ts file for a JS library is the hard
part.  If I am understanding it correctly, almost every d.ts file (for a JS
library) is hand-coded.

If we have a tool that converts a majority portion of that d.ts to a d.as
file, going in and hand-coding things to fit an AS3 paradigm should not be
very hard.

Also, these are one time conversions.  We could do it for a few popular
libraries and set the ball rolling. Hopefully, the community will start
chipping in to create a bigger collection of d.as files as time goes.

It should be possible because, typescript compiles down to javascript.  And
d.ts is a regular typescript file as well.
