This isn't clear,
Pass by Reference
If you want to pass more than one array or hash into a function--or
return them from it--and have them maintain their integrity, then
you're going to have to use an explicit pass-by-reference.
Perhaps this is better,

No, you can pass a single hash in directly:
#!/usr/bin/perl
sub a {
my %b = @_;
print $b{wibble} . "\n";
}
%c = (
wibble => 'hello'
);
a(%c);
