[antlr-interest] yet more thoughts on error handling / recovery

[Terence Parr]

Howdy,

Got some interesting details written down for error recovery and 
reporting (thinking about auto insertion/deletion for token mismatches, 
dynamic paraphrases, and dynamic resync token sets).

http://www.antlr.org/blog/antlr3/error.handling.tml

I would love the following (particularly for debugging grammars):

line 20:12: expecting ID found LPAREN
         at: methodDef : (access)* returnType @ ID (<args>)? "{" ...
      input: ... public static void @ ( int x ) { float ...

where the @ indicates the position.
