How many of your patches actually use [route symbol]? 

(In general to strip off selectors, [list trim] should be used nowadays.)

Object behaviour is vocabulary - you have to memorize it for each object
separately just like irregular verbs. The message system with selector and all
that is grammar that describes the general rules to form sentences. The message
system itself is easy - it almost fits into this: "a message is a selector +
data". Memorizing all objects of course is hard(er), and indeed there are some
inconsistencies in objects like [route] stripping off list-, but not

But all these things are behaviours of single objects and thus vocabulary. You
could write a [route] which would strip off the symbol-selector of "symbol
pitch" or which would not strip off any list-selectors. Or build a [symbol]
that does accept non-symbol-messages or even floats into its right inlet. Maybe
someone already did it as an external.

But they would be different objects - and would still work with the same
message system grammar of Pd.
