There was a problem hiding this comment.
Suggestion should also include the exclamation. i.e. println! instead of println.

Fixes #13677 This does the same sort of suggestion for misspelt macros that we already do for misspelt identifiers. Example. Compiling this program: ```rust macro_rules! foo { ($e:expr) => ( $e ) } fn main() { fob!("hello!"); } ``` gives the following error message: ``` /Users/mcp/temp/test.rs:7:5: 7:8 error: macro undefined: 'fob!' /Users/mcp/temp/test.rs:7 fob!("hello!"); ^~~ /Users/mcp/temp/test.rs:7:5: 7:8 help: did you mean `foo`? /Users/mcp/temp/test.rs:7 fob!("hello!"); ``` I had to move the levenshtein distance function into libsyntax for this. Maybe this should live somewhere else (some utility crate?), but I couldn't find a crate to put it in that is imported by libsyntax and the other rustc crates.
