Of course there is. This is exactly what defining a constant function
pointer and assigning is to the correct implementation does (with no code
whatsoever). This is what Charalabos has sucessfully implemented.

I don't recall ever discussing this. Just because it has been that way for
2 years doesn't make it right.

Why implement the same function 8 times (as in Uppercase) when just a single
implementation is needed. If we later create a faster implementation for a
particular target, it can be easily added.

By duplicating the same function 8 times, we could be creating potential
problems further down the line. If for example, we later find a bug on a
particular target, It would be very easy to correct the target version, but
overlook the other identical functions.

regards,
John.
