When we get "Unexpected token" error from the tokenizer or parser, we currently just show:

Unexpected token: "..." at <line>:<column>

In addition it'd be good to show an actual line from the original source, and a pointer to the invalid token:

foo + &7;
      ^ 
Unexpected token: "&" at <line>:<column>
