Um, finding out if a line "hits" any shape.

I need to find out if a line, with start position and end position specified, hits any shape and what position it hits it at.
I know I could use polygonShape:testPoint(x, y); but that would mean I'd have to test every position on the line, which could be bad as you can imagine. Any ideas?
Any ideas?

This function exists in Box2D, but looks like I forgot to wrap it.
Lame.

Are you ever going to add joint:Remove() body:Remove() etc?
I know about the collect garbage thing but it would be nice to have them, they work if used correctly no?
