Yes, ref()
if(ref($refofsomekind) eq 'SCALAR') { print "You are a scalar reference"; }

Hmmm abit more complicated but doable:
if(ref($originalref) eq 'ARRAY') {
print "The original referenc is an array ref\n";
for(@{$originalref}) {
if(ref($_) eq 'ARRAY') { print "I have an element that is an
array ref"; }
# or count each type or whatever
...
}
} elsif(ref($originalref eq 'HASH') {
print "The original reference is a hash ref\n";
for(keys %{$originalref}) {
...
}
}
perldoc -f ref
