Lingua::Romana::Perligata – Perl for the XXI-Imum Century (2000)

Which is no surprise in the latter case, given how strong of an influence Perl was (and still is, though nowadays to a slightly-lesser amount) to Ruby.

My point, though, was that this "Perligata" still feels like Perl (though with keyword-heavier syntax like sic/cis and such, perhaps it leans more toward Ruby in look/feel, which I don't think is a coincidence). You could probably implement this in, say, Java or Go or Python, but it probably wouldn't feel a whole lot like those languages in terms of expressiveness.
