Should have added that this opens the path to interactive playgrounds for Perl programming, as long as it doesn't include XS.

This means we could add a test page here to try out Perl code without the need of pre bundling all modules, hence keeping webperl small.

Concerning XS, I'm no expert in WASM and C, if it's possible to have more than one instance running one could probably do the dynamic linking via a JS bridge. ...
