just quickly,

Here's a slightly shorter version that still compiles under strict and warnings. i only have tested it under the single test case above, if it fails others please provide them and i'll try to correct it. Anyway, this weighs in at 66 characters:

sub Harmonics ($$) {
#23456789_123456789_123456789_123456789_123456789_123456789_123456789_
for$a(1..pop){$_{sprintf'%.3f',$_[0]*$a/$_}++for 1..$a}sort keys%_
}
