2015-10-25	libsyntax: better error for lifetimes in patterns	Kevin Butler	-0/+16
	Previously, if you copied a signature from a trait definition such as: ``` fn foo<'a>(&'a Bar) -> bool {} ``` and moved it into an `impl`, there would be an error message: "unexpected token `'a`" Adding to the error message that a pattern is expected should help users to find the actual problem with using a lifetime here.
