The same feature is available in any language with a decent FFI (must support loading an arbitrary shared library, marshalling/demarshalling data between languages, and invoking functions in the shared library).
This is possible in Python, Ruby, Java, Racket, Rust, Perl, Go, and plenty of other languages I'm forgetting or haven't used. Yet who would seriously argue that "Python is compatible with Perl" because you can embed libperl in a Python program?
You might as well argue that "Rakudo is compatible with libssl", for all the relationship Rakudo source code has with Perl source code.
