How about this? 
sub flatten {return "@_"};

if ( flatten(%hash1) eq flatten(%hash2) ) {
        print "equal\n"
} else {
        print "not\n"
}

This will compare the keys as well as the values, so if the same values are fixed to different keys then it should still return false. The 'stringification warning' above applies, i.e. this might have a problem with fractional numbers. Should be ok with strings and integers though.

PS If anyone can tell me how to get this hash-flattened-into-an-array behaviour without a sub, I'd be interested. I've been fiddling around with the syntax trying to get that.

PPS Can two hashes with identical keys and values ever store the keys in a different order? I've been assuming not, but if they can, then the above won't work reliably. Again, would be interested in info... or a pointer to the correct RTFM... on this.
