I've run into the need for lexer/parser feedback myself, specifically
processing interpolated strings (that contain expressions from the outer
language) in Reia.  I haven't found a good solution.  Interpolation works
but only on a subset of expressions... for example you can't nest strings
within strings.

Have you thought about using neotoma?
