I guess you'd have to call

     mycounter.inc

in which case there's still a method call involved. So the only difference
between that and

     mycounter = mycounter.+(1)

is the passing of an extra argument, and assigning an object reference to a
variable. My gut feeling is that both of those are fast operations.

You can eliminate the extra argument by doing

     mycounter = mycounter.succ

Cheers,

Brian.
