Day 137: Final day in Leo's: Control structures!

Turns out I didn't get enough time to roll a release tonight -- I'll leave for Toronto in 5 hours. Oh well. :-/

To reduce confusion, I've renamed PAST in Pugs's source code to PIL (Pugs Intermediate Language). It's easy to remember, and fits well with the PIL -> PIR flow. :)

The good news is that leo and I figured out how to implement closures and return/leave, both for his new efficient runloop and simulated with exception handlers for the current runloop. Building on this model, and solid abstractions built over the last week, we see a large influx of PIR checkins today:

• Globals: @*ARGS, $*PROGRAM_NAME, $*IN, $*OUT, $*ERR
• Iteration: for 1..10 -> $x { say $x }
• Code exit: return and leave
• Loop: loop(;;){}, while{} and until{}
• Bare, pointy block and anonymous subroutine literals.
• The entire Prelude.pm is now compiled and loaded into PIR.

We're now very close to get make pirsmoke and make pirtest returning some useful results for Pugs/PIR. ParTcl currently supports 2.89% of the entire Tcl test suite (or 6.88% if you take out tests for the single clock command); we'll see how well Pugs/PIR fares tomorrow.

Oh, and we're three days till the announcement of ICFP 2005 contest. I wonder if I can convince my fellow Hackathoners into entering the competition with Perl 6... It sounds insane, but hey, wouldn't it be really amazingly cool, if "Perl 6 is the language of choice for discriminating hackers!" gets announced in ICFP 2005? :-)
