This is a new implementation of PAST, the Parrot abstract syntax tree. It's still somewhat early, only simple PAST nodes are available, but it will expand rapidly as we identify more features to be added.
PAST also needs documentation. In lieu of documentation, the best examples to look at thus far are in "abc" in languages and "perl6" in languages.
To install Parrot::Op, copy and paste the appropriate command in to your terminal.
cpanm
cpanm Parrot::Op
CPAN shell
perl -MCPAN -e shell install Parrot::Op
