Huon Wilson	441044f071	Update compile-fail tests to use is/us, not i/u.	2015-01-08 11:02:24 -05:00
Patrick Walton	a5bb0a3a45	librustc: Remove the fallback to int for integers and f64 for ... floating point numbers for real. This will break code that looks like: let mut x = 0; while ... { x += 1; } println!("{}", x); Change that code to: let mut x = 0i; while ... { x += 1; } println!("{}", x); Closes #15201.

Huon Wilson	f2a137829e	syntax: desugar a for loop to a let binding to get better error ... messages when the pattern is refutable. This means the compiler points directly to the pattern and said that the problem is the pattern being refutable (rather than just saying that some value isn't covered in the `match` as it did previously). Fixes #14390.	2014-05-27 09:24:37 +10:00
