Larry apparently is going to static parsability in Perl 6.
You seem to be missing a "not" in that sentence.

The last time I brought this up with Larry, which was admittedly a year ago, he wasn't going to budge on either of the dual-nature of "/" or the ability to prototype a subroutine to influence the number of parameters.

Indeed, part of the difficulty in having implemented Perl 6 so far is not being able to have a clean lexical phase, thanks to this wonderful "perfect storm" of desirable features. You must execute Perl code at compile time, even in Perl 6, in order to even tokenize the remainder of the file.

The only concession I heard from him is that the results of that executed code would not be promised to be carried forward into the result of the compilation, which seems a bit odd, as it would break things like:

my $x; BEGIN { $x = time }
Unless the BEGIN block is executed both at compile time and once at pre-run time.

Of course, I might be a few months out of date. I got bored following all the Perl 6 stuff, so I'm working on Smalltalk for a while until Perl6 gets a bit closer to a release.
