It doesn't affect the parser module.  For now, the same parser is
used, so the parser module can still work the way it does.  If we
changed the parser in the future, well, the parser module would
change, too.  I'd also like to add an analogous ast module that
exposed the abstract syntax tree for manipulation, along the lines of
the parser module.  Not sure if we'll actually get to it for this
release.
