P5 also has inline python, but it's nowhere near as easy as using a native library.
Stefan Seifert authored or maintains both the P5 and P6 versions of Inline::Python, the Inline::Perl5 for P6 and the Inline::Perl6 for P5.
Three of the four are at the first stage. They work in much the same way, using `.run( ... )` to run a line of code at a time.
One of the four is at the second stage. It works as easily as using a native library. No need for `.run` etc.
Are you aware of the compatibility with Perl 5 that I mentioned in my prior comment in this thread? If so, why do you discount it?
