[antlr-interest] tree walking errors to line/col

[Bryan Ewbank]

I'm not sure about "best"... What we've done is to capture file/line
as we tokenize the input, then keep that info on the nodes generated
from the tokens.  For generated nodes, we just chase the
"getFirstChild" - by construction, we guarantee that there's a token
with file/line somewhere down there.
