First whack at defining semantics of MAIN subs.
Congradulations! That is SUCH a great idea.
Since Perl didn't have the concept of an explicit 'main' before like
many other languages, I had been doing this for a long while in my
non-tiny Perl programs, to make code easier to read, more consistent,
and properly isolate conceptual lexicals from conceptual
globals|constants:
# 'use' statements
# declare constants
main();
sub main {
...
}
sub other {
...
}
# etc
Or alternately I did:
# 'use' statements
# declare constants
MAIN: {
...
}
sub other {
...
}
# etc
And now there is a MAIN() that implicitly gets called, so no more
"main();" invoke or "MAIN:" anonymous block.
One great thing that somehow I never thought to ask for.
And of course, the actual implementation is a lot better, with all
the various command-line options|args being mapped to normal Perl 6
args in an easy to understand and powerful way.
The default USAGE() sub was a great idea too.
I am SO going to use this.
