Let's go back:

Instead of time units, let's take the incoming single-selector "pi" and replace it with 
the float value of pi for any object that doesn't have a "pi" method or an 
"anything" method (but does have a float method).  Furthermore, if a class defines a 
float argument but the argument provided isn't a float, then check first if what it received 
was A_SYMBOL 'pi' and if so replace with the float value of pi.

Is what I wrote above possible to do without causing huge problems to performance or 
creating ambiguities?  Is it something people would look at as a feature, or a nuisance that 
makes it harder to learn Pd?  If the answer is that something like this constant expansion 
is a bad idea then there's no point discussing macro expansion for time units.
