Or, assuming you might want to generalize to N dimensions someday, just
sub bar ([EMAIL PROTECTED]) {...}
and deal with it as in Perl 5 as a variadic list. I suppose one could say
sub bar ([EMAIL PROTECTED] is shape(3)) {...}
and get checking on the argument count.
if I understand correctly, without using multi subs:
sub bar(@coords is shape(3)) { ... }
bar(@xyz); # ok
bar( [$x, $y, $z] ); # ok
bar($x, $y, $z); # compile-time error
while:
sub bar([EMAIL PROTECTED] is shape(3)) { ... }
bar(@xyz); # ok
bar( [$x, $y, $z] ); # ok
bar($x, $y, $z); # ok
bar <== $x, $y, $z; # still ok
am I right?
cheers,
