Re: Checking whether two variables have the same structure

For some reason, using your code I get...
```
   ...
   \$foo -> oS
   ...
```
which doesn't seem quite right.

I gotta side with George_Sherston on this one, It's all about Data::Dumper. Here's what I can up with for generating the grammer described (I think it can handle any case the orriginal post did)...

sub my_describe {
    my $s = Dumper(@_);
    $s =~ s/\'[^\']*\'//g;  # eliminate scalars
    $s =~ s/[^\[\{\'\\]//g; # cut to the heart of the structure
    # + because we only care about one member of hashes/arrays
    $s =~ s/\[+/Ao/g;       
    $s =~ s/\{+/Ho/g;
    $s =~ s/\\+/r/g;
    return $s . "S";
}

UPDATE: I just realized this can't handle something really basic: \\\\\\$foo. Oh well, that's why version numbers were invented
