Re^3: Builtin functions defaulting to $

You don't have to memorize which symbols are true globals either.

which will relieve a lot of grief. Like with $! and $@ which may get overwritten if not dealt with in a timely manner. If I well remember, $! will be just a reference to what the current error looks like; therefore the question: what's $@ in Perl 6, if it exists at all? I could think of that as a list of messages of what things blew up from there to here (ie some "exception stack trace excerpt") - but then, that would be more appropriately @$! (in perl5 syntax, that is)...

update: reading again, not "have(ing) to memorize which symbols are true globals" means: there are no true global symbols, right?

--shmem

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /

There is no `$@` in Perl 6; all errors are unified into the `$!` object, which can hold all the info it needs to. And in general, those few remaining punctuational variables are all lexically scoped. But what I meant was that you don't have to remember that names like `STDIN` and `ARGV` are the same symbol in every package. Those are now spelled `$IN` and `@ARGS`, where the `*` indicates true global scope; or perhaps just membership in the `GLOBAL` package, which as you point out arguably means there are no true globals.

$@

$!

But what I meant was that you don't have to remember that names like STDIN and ARGV are the same symbol in every package. Those are now spelled $*IN and @*ARGS, where the * indicates true global scope; or perhaps just membership in the GLOBAL package, which as you point out arguably means there are no true globals.
