In Interaction between languages in Parrot, chromatic wrote parenthetically: nit: Perl 6, with the space please.
Why? And more important, what makes the distinction important enough to make? Is this a deliberate attempt to out-shibboleth [Pp]erl[ ]?5?
The responses indicated that everyone clearly understood what language the OP was referring to when he mentioned "Perl6", so the important thing - communication - was achieved. And unless the p6 community has created or is about to invent distinct meanings for "Perl6" and "Perl 6", I don't see the potential for miscommunication in the future.
I fear this sort of pedantry, aimed at people that have not yet made the jump, will unnecessarily drive people away - and I am sure the spark of an aside today will feed the forest fire of future flamewars.
Please leave pedantry to the compiler. It knows what it wants, and it usually has a good reason for it.
