Hi!
That will only work until someone asks for a function on a differt
type :)
Flexibility is a win. For instance a user may want to write their own
type.
Cheers,

Implementing 'now' as a manifest constant rather (or in addition
to) a pseudo function has much going for it. You can also do
'today', 'tomorrow', 'yesterday', and 'Ann\'s birthday', though
the latter is probably less general.
If you did it as a constant, every time you wanted to add a new
function you would be modifying an enum. Removing a function? Still
sounds bad.
Using a string to match with knowledge that it was a function that
was asked for works. One further step might be to identify the
version of the function that existed during the creation just to be
on the safe side. Or hell... implement COM :)
No, just extend the string to date conversion function. Highly
localized, fast, and completely general.
