Evening All,
Eponymous templates allow a nice calling syntax. For example,
"foo" here can
be called without needing the exclamation mark (!) at calling
sites. We see that
foo is restricting a, and b to be of the same type ... so far, so
good.
auto foo(T)(T a, T b) { ... }
Now, suppose I need to restrict "T" only certain subsets of
variable types.
I can imagine putting in some "static if" statements in my
function body,
is one solution. (Also a bit ugly as the allowed types might
grow).
Is there a more elegant way, to do this?
Regards,
James
PS Any violations should be caught at compile time.
