...except that this is a Rakudo bug, and Rakudo doesn't have a REPL. It has a REL, but if you want P, you have to arrange it explicitly. I would much prefer a REPL, but I imagine that's not way up the priority list at the moment. (Keeping lexical state across interactive statements would be nice, too.) Pugs, of course, does have a P-ful REPL. This led me to wonder if there's any intent to include the interactive behavior of the interpreter as part of the spec. I can see arguments for leaving it up to the individual implementation, but it'd also be nice to have some consistency there. Maybe not require that there be a REPL, but supply some guidelines for how it should behave if it exists. Since Perl 5 has no REPL, I'm not sure where such a spec would go. S20, maybe, since the debugger is the closest thing? Sorry if this has come up before; I did a quick search but didn't see any discussion of it. -- Mark J. Reed <markjr...@gmail.com>
