Now THAT's what I call an overloaded operator! ^_^
it's not really overloaded, it's *loaded*. if you type
a := 1
in an r session without defining '=', r cannot 'find such a function',
but it doesn't complain about invalid syntax. so there is the operator,
only that it's not operational.
But seriously: can someone explain to me what's going on in the rvalues.r code?
i think i-the-sinner'd be the right person to ask. i'd suggest to discuss offline, because rvalues is really an experiment, a proof of concept, and as such may not be of interest for wider audience. (it might be that it will be developed into something substantial, but no guarantees.) vQ
