Mildew
SMOP is a runtime engine designed and developed by Daniel Ruoso. It's build to run the product of several Perl compiler side by side. Maybe this could lead to Perl 6 interpreter that can delegate the execution of well known and important modules to the perl(5) interpreter. Currently there is only one Perl 6 frontend (mildew), since developement of kp6 is stalled. Mildew also uses the STD.pm for parsing and is able to produce javascript that can be run in a browser.
