I prefer your current way to the Max/MSP-oriented way that 
[expr] does it.  I find the [expr] way particularly ill-suited to 
Pd since Pd strips away unnecessary decimals and decimal places, 
thus making it look like it's Max-compatible when, depending on 
where the user puts whitespace, it may not be:
[expr 2.0/3] is the same in Max/Pd
[expr 2.0 /3] is not

It's tricky.  You could add a function that takes 
no arguments which means, "Don't output."  But then I think it 
would be more useful to have a flexible if, then, else syntax 
where you can specify the outlet explicitly.  Maybe that means 
this is a separate object than expr.

I read the Max 5 documentation and they have if and else 
functions where you specify the outlet with out1, out2, etc.
