There is a solution to this:

1) If a file compiles successfully, then use ASIS.
2) If a file compiles with errors then first use ASIS and then do
grep.

The key to this is how thin a layer ASIS is. Regenerating of "ASIS
data"
sounds like data transformation: from an AST to ASIS objects.
Perhaps, this can be avoided.

There is some mention of JSIS(Java) but the link leads
to an unrelated site. A C interface would be very handy
for a C implementation.

Thanks.
