What, so I can set a source filter to (say) "match only on barewords
that are in locations where builtin keywords would be recognised?"
so for my script:
print <<print
print
obfuscation
print
only the first "print" gets passed to the source filter as a candidate?
or one could match on the strings inside // ?
or on STDOUT that is a filehandle
[not the world's best example for what I'm trying to saw, which is that
currently I suspect any filter you want to write really has to cope
with parsing the entirety of perl to try to find the pattern you want
in the syntactic context you're interested in.]
