in reply to Perl 6 - Operator renaming

Losing the . for concatenation is going to be painful. I understand that it'll go a long way to help non-perl developers do OO perl to have it be the same as in most other languages, and we need to steal the dot for that, but man, I concatenate a lot. And ~ is hard to type.

    Yea, I used to dread the idea of using ~ for concat. However, Perl6 does have string interp. In addition, Perl6's string interp. will be even more powerfull than 5's. So, we may find ourselves using ~ less often than we might think.

    ($$<<$$=>$$<=>$$<=$$>>$$) always returns 1. :-)
      Also, ~ will be used to introduce string context too. So it may take a while, but first or later we will all get used to associate it to strings...

    There are still many ways to avoid needing the tilde. There will be normal interpolation as in Perl 5 ("$foo$bar") but new is interpolation of closures ("int($baz) = { int($baz) }", resulting in something like int(5.6) = 5). There is also sprintf, now know as "as" ([$foo, $bar].as("%s%s") or maybe also "%s%s".as($foo, $bar), which may not make sense at first, but will make sense when written as as "%s%s": $foo, $bar).

    Personally I don't find ~ hard to type, and I absolutely love its place in Perl 6, not only as the string concatenation operator, but also as the string context operator and the stringy semi-meta operator in bit operators.

    Yikes, I didn't know they were changing so many basic things! I'm officially scared of Perl 6 now. That tilde just seems extremely unintuitive. I'm worried Perl 6 might be going the Python route and trying too hard to be different from every other language.
