I recently came across this impenetrable Wall code:

  last|perl -pe '$_ x=/(..:..)...(.*)/&&"'$1'"ge$1&&"'$1'"lt$2'
  That's gonna be tough for Randal to beat...  :-)

What on earth does this do?  I get no output when I run it on my Linux
system.  ( >*gulp*< )

Is there any tool that would help decoding this thing?

Thanks,

kj
