How to replace a string with one of a few alternatives?

[Marcin Borkowski]

Hello fellow Emacsers,

I'd like to query-replace a string with one of a few alternatives.  The
catch is, I'd like to select an alternative for each and every
occurence.  Is there a ready-made solution for that?  It should be
rather easy to hack, using query-replace-regexp and \, with some
function to select one of the alternatives, but why reinvent the wheel
if it's already done?

TIA,
