To be honest, it's mostly just a reaction to new things. I'm always a little grumpy before I absorb stuff.
- Submethods throw me a little, but I expect to get the hang of it.
- New funny characters ($.instancedata and %:classstuff for starters) throw a little more for the folks who like to refer to Perl as line noise.
- Not drinking enough coffee when you're really used to it can induce mild headaches as well. Doesn't have anything to do with Perl 6, but might have had something to do with my attitude this morning.
The (admittedly somewhat snide) comment about maintainability was not about the look of Perl 6 OO itself, which I am looking forward to using and abusing. The comment was based on thinking about what potential impact this might have on the code of folks who like to use every language feature in every file of code they write. But I've had my coffee now, and I've had time to think about it, and I'm okay.
I just want to get in there and start using Perl 6. Not approximations from the Perl6 modules of CPAN, but the actual language. I think I'll go play with Parrot for a little bit :-)
Update: Yeah, playing with Parrot. Where there's a lovely Perl 6 implementation. The new problem is that it's almost 3am and I really should be in bed. Just ... you know ... disregard pretty much the whole thing.
