Of course, except it will then be multiple parameters (one
for each element of the array) instead of one parameter.
I'm surprised you didn't just experiment and see what happens. :)
EG:
my @result = my_splice (@taborig);
sub my_splice {
my @array = @_;
}
It's usually simpler to just use a reference though.
my @result = my_splice (\@taborig);
sub my_splice {
my $aref = @_;
}
If you like, you can immediately turn it back into an array
my @array = @$aref;
or just deref the ref in the sub when you use it :
@rslt = splice @$aref, ...
