Creating a formal language definition, perhaps?

Consider what happened to JavaScript 1.0 after it evolved to ECMAScript.

But doing this in Perl would lead to a logical paradox, unless it's a reduced simpler Perl for bootstrapping the definition.

Not to mention the whole thing would probably be awfully slow. And it would probably be a compromise anyway, if the plan is to reach full Perl compatibility. I mean, how would you load C-Libraries, for example? You can either do that in the underlying Perl binary, or you start including a whole C/C++/machine code interpreter... A limited/reduced/simplified Perl interpreter certainly has its use cases. But if you need a full-blown Perl installed to run it, that somewhat defeats the point. Now, a somewhat reduced and limited Perl written in JavaScript, that could be damn useful for web development. PerlMonks XP is useless?

I'm not sure why you are talking about performance now. ECMAScript's language specification led to many competing implementations. And having an alternative implementation of Perl would naturally involve the need of a specification and/or help define it. > Now, a somewhat reduced and limited Perl written in JavaScript perlito was already mentioned twice in this thread. Haukex' webperl is feature complete (not "reduced") but it's not written in JS (apart tiny parts for bridging), but cross compiled to WebAssembly Cheers Rolf _{(addicted to the Perl Programming Language :) see Wikisyntax for the Monastery}	[reply]
