Previously the parser printed parse errors with Debug formatting, even
though Display formatting is implemented and looks much better.
Before:
?- load libstd.chalk
?- forall<T: Clone> { Vec<T>: Clone }
error: parse error: UnrecognizedToken { token: (8, Token(17, ":"), 9), expected: ["\",\"", "\">\""] }
position: `forall<T: Clone> { Vec<T>: Clone }`
^
After:
?- load libstd.chalk
?- forall<T: Clone> { Vec<T>: Clone }
error: parse error: Unrecognized token `:` found at 8:9
Expected one of "," or ">"
position: `forall<T: Clone> { Vec<T>: Clone }`
