Right, but that punishes the Pd users by making them use Max notation to force 
floating point math, and it confuses the Max users coming to (or porting patches 
to) Pd, who learn Pd's float-centrism then are forced to relearn some 
bizarro version of Max number types where spaces matter.

But I wouldn't call that a bug because I can't remember if [expr] claims to be 
Max-compatible or not.
