I've spoken something Perl 6 at my work place the first question is about whether there's a production ready version of it. A negative answer leads to a ridicule that it has taken more than a decade now for this thing to come out
then your co-workers oppinion is the same as mine, I mean if you want to write something in Perl6 and you discover that the compiler has bugs(that you'll most likely be unable to fix) then you'll be very discouraged and will consider that whatever code you write in it is standing on moving grounds.
so what I mean is, it's risky to write code in such a language if it's not production-ready.
not only risky for work(which is obvious) but even if you're on your own time doing stuff, you're probably wasting it because the compiler isn't yet finished.
