Rename fn*() to fn() as originally planned. 2012-01-18 20:10:51 -06:00			`fn call_any(f: fn() -> uint) -> uint {`
treat fn() as fn&() This is not my ideal way of going about things. I'd prefer not to have expressions typed as fn(), for example, but I couldn't get that to work together with inferring the modes of arguments and other corner cases. 2012-01-18 14:04:07 -06:00			`ret f();`
			`}`

			`fn main() {`
			`let x_r = call_any {\|\| 22u };`
			`assert x_r == 22u;`
			`}`
