That's exactly right.  In fact, 100::ms +=> now is the formal, more 
semantically "correct" syntax, and 100::ms is a "shorthand".

That would be a bug alright!  I repro'ed on windows and os x, and have 
tracked down the problem to incorrect emission of instructions for +=> 
now. It's now fixed in CVS.  I wonder how long that has been broken...
Apparently no one actually uses +=> now, huh huh.

Best,
