Likely:
 All likely tasks are done...

Maybe (4.0):
 {7} Make pcre/reg{perl,posix}.c handle [[=x=]] and [[.x.]] and MBCS
 {6} Add DFA ability to reg{perl,posix}.c, maybe (or maybe not)
     taking inspiration from the old rx code.

Unlikely (3.5x):
 {5} Add -N addressing (e.g., -3,/bar/ s/foo/bar/) (requires
     lookahead).
 {4} Generalize + (and possibly -) addressing (e.g., /foo/+3,/bar/-2
     s/foo/bar/).
