Having a lexer in Perl is useful, but does it have to be built into
the core? There already are several lexer modules for Perl 5
(Parse::Lex, Lex, Parse::RecDescent...) and while they may be
benefited by certain small, sharp additions to Perl, they do rather
well outside the core (and it means the Perl 6 developers don't have
to add Yet More to their plate).

That might be handy, its been getting easier to do this sort of thing
in a regex but its still a bit less-than-obvious. Non-obvious enough
to require its own module: Text::Balanced.
Can't comment on the particular syntax you've chosen, but the idea
sounds useful.
