b96c3477f8edd414b9be5670f3912f7cb15eab1e exp/regexp/syntax: syntax data structures, parser
Parser is a work in progress but can populate most of the
interesting parts of the data structure, so a good checkpoint.
All the complicated Perl syntax is missing, as are various
important optimizations made during parsing to the
syntax tree.
The plan is that exp/regexp's API will mimic regexp,
and exp/regexp/syntax provides the parser directly
for programs that need it (and for implementing exp/regexp).
Once finished, exp/regexp will replace regexp.
