It *could* do this, but loading bytecode in Perl 5 is slower than loading
and compiling source, so there's not really much point. What's so magic
about bytecode, anyway

As it stands, though, perl6-internals isn't about perl, but Parrot ...
so of the two lists, language is arguably more appropriate...

The Perl 6 Summary for the week ending 2004-09-03
Another week, a free weekend, and still I haven't started writing the
summary until Monday. Still, I don't actually start at college 'til next
week, so that's all right then.
We start with perl6-internals.
Compile op with return

Not if it's slower, no. The choice was made not to go with bytecode because
of a deficiency in Perl. If that deficiency wasn't there, then sure, go
with bytecode.
But you're mis

Another possibility is that .[] always forces the "normal" view of an
