Huon Wilson	b1931e48a0	lint: only consider actual calls as unconditional recursion. ... Specifically, just mentioning the function name as a value is fine, as long as it isn't called, e.g. `fn main() { let _ = main; }`. Closes #21705.	2015-06-29 15:59:37 -07:00
Huon Wilson	fbef241709	Add a lint to detect unconditional recursion. ... E.g. `fn foo() { foo() }`, or, more subtlely impl Foo for Box<Foo+'static> { fn bar(&self) { self.bar(); } } The compiler will warn and point out the points where recursion occurs, if it determines that the function cannot return without calling itself. Closes #17899.	2015-01-25 00:21:03 +11:00
