"Usually"? Probably not. "If necessary"? Yes. Not sure of the ratio of
direct calls to conversions over the total set of functions and
operators, but if the result is not likely to change with a conversion
step then I feel less of a need to implement Yet Another Function to do
the direct call.
Glad the function (documented in the, uh, documentation ;) worked for
you.
