If you say so. I was just saying that the default should avoid the
all-encompassing conversion and not try second-guessing the users'
intentions. It's probably safe to have Pd convert a symbol to a float by
default iff there is no symbol method and there is a float method.
Trying to interpret every possible string as a float would add huge
amount of bloat and delay to core Pd.
