I think that the proper thing to have done would have been to write a new CPAN module that's "exactly what you needed," then share it. Nevertheless, it's impossible for every language to be everything to everybody. That's why we invented – and, very regularly use – more than one programming tool. Why try to "re-create gprolog in perl when you've already got gprolog? Why dumpster-dive into "WebASM" if your only motivation for doing so is to say that you have done it? There's utterly no point.

rust recently appeared as a brand-new language because a group of engineers realized that they were facing a brand-new use case that other languages didn't yet cover. So it goes. Perl is a venerable tool in a society of tool-builders.
