Naming conventions for optional parameters

[Dar Scott]

I noticed at here...

http://www.fourthworld.com/embassy/articles/scriptstyle.html

... a naming convention in which parameters are named as such:

pLength


I wonder if folks use an alternate prefix for optional parameters.

These usually fall into two classes.

The first is the tail-optional group.  These are dropped from the 
right.  They may contain empty which is distinct from being missing.  
These are tested with paramCount().

The second is the empty-means-default group.  These may be replaced 
with empty at any place in the parameter list and also may be dropped 
from the right.  These are tested with "is empty".

I'm considering using an alternate prefix for these.  Will this help or 
will it muddy the waters?

Maybe, to comply with the above, they can be "pt" and "pe".

Example:

on toast pToaster, peTemperature, pBread, peNumber, ptProfile, 
ptAnnouncement, ptReport

An alternative that doesn't use prefixes is this (which limits classes 
to one):

on toast pToaster, pBread, /* optional: */ pTemperature, pNumber, 
pProfile, pAnnouncement, pReport
