Dear monks,

Is there a way to give names to bits as in a byte bit field whose every bit would have a meaning that could be set by a subroutine, like: 

  setStatus(powerOn);

[download]

... which would set the powerOn bit in a 8-bit status byte. This bit could be the first one, bit 0. Then we could have: 

  setStatus(lightOn);

[download]

Which would set another status bit in the same status byte while not modifying the other set/unset bits. So on so forth.

Is there some kind of enum type in Perl to do that ? Or can it be done using a hash ?

Thanks.
