I would call it a bug, since both forms should work.
They've done some work on Message Box execution context recently, and
perhaps that's where the chance occurred, but while I haven't looked at
RunRev's MB code I know that in MC any expression that doesn't have a
command is internally turned into one by prepending "put" on it so that
it can be executed.
I wonder if the issue here may be that the latest version of the Message
Box is always prepending "put", even if a "put" is already there, which
would give us things like:
put put myFunction("foo")
...which would of course be invalid to the engine.
