See also the git repository. * 0.03 - fixed various bugs in Subpattern ->walk. Subpatterns now close over what they point to at time of object creation instead of at walk or ->render time. * 0.02 - Subpattern calls ->render on objects; this allows subpatterns to be not just simple strings. croak/confess instead of die especially if deep in some ->render or ->walk tree. Add ->walk so the parse tree can be walked through with (and possibly modified by) a callback. * 0.01 - released on a mostly unsuspecting world.
