Ah indeed. In fact the current syntax is:
pub fn init<T: Copy+Send>(...)

You shouldn't have a comma between Copy and Send. It thinks Send is a
type parameter, and it can't infer a type argument since Send doesn't
appear in the signature.

Sorry if it wasn't clear, but the body of glut::init is included
in the pastebin snippet I posted. Line 15: pub fn init<T: Copy,

I tried adding the GLUT<int> annotation to the function, and got
the same error:
main.rs:10:4: 10:14 error: cannot determine a type for this
expression: unconstrained type
main.rs:10 <http://main.rs:10> glut::init(move initial,

That is somewhat surprising to me. In some cases you do need type
annotations but I wouldn't expect one to be required on that line.
Can you give a larger snippet, including perhaps the body of the
function you are calling?
Also, you can try an explicit annotation:
glut::init(~1, |glut_s: GLUT<int>|) { ... }

I'm trying to create a function which initializes a generic

the error that is the subject. I have no idea why this is
happening. Anyone have any tips?
