[REBOL] Re: Set on path values

Hi Gregg,
Thanks! This worked first time around. I was apprehensive of the binding of
the expressions to be evaluated as path members, but this was fine. Is that
the magic of [do val]?

Something like this?
incr: func ['val] [do reduce [to set-path! :val 1 + do val]]
