The legendary TimToady pointed me in the right direction. First, STD.pm and the scripts for using it live in the Pugs repository. I got
http://svn.pugscode.org/pugs, though it may be possible to just get the
src/perl6directory tree, as that is the one we are interested in.
Once you have that
cdto it. You need to
maketo get it ready to use. Unfortunately, it is hardcoded to assume Perl 5.10 is available in
/usr/local/bin/perl. If, like me, you only have 5.10 installed as a local user, you will need to go through the code and replace that path with the path to your Perl 5.10. (This is a great application for a quick Perl script.) You also need to have
YAML::Syckinstalled. (I should thank moritz and PerlJam for helping me with getting this directory prepped to work.)
If you get that all set up and execute
makeand it doesn't return any errors, then you should have a working
tryfilecommand will try to parse your Perl 6 file carefully and provide sensible error messages.
