Hi,
I just wanted to say, it's funny how I did the *EXACT* same thing only **a few
days ago**:

Not counting the braces, the actual code is just 4 lines for the compile-time
version, and 5 lines for the run-time version. The page above only has a link to
one of these; both of the versions are here:

Pretty short, eh? I doubt that it can get any shorter than that code. :) Feel
free
to use my version inside the library. ("I hereby release the code to the public
domain," to cover the legal stuff.)
Wow. I swear I didn't see this! "Great minds think alike" eh? :o)
I think your implementation that defines the function directly is
better. However, when we plan to make the whole thing work with
overloading, we'll probably want to go with the template solution.
BTW, right now ParameterTypeTuple catches the lexically first overload
or something. Instantiating memoize!sqrt latches on sqrt(float). We need
to generalize ParameterTypeTuple to work with overloaded functions. This
is where implicit flattening of tuples is going to turn a bit troublesome.
