Good day to all!
I've been thinking. In D you can write a similar design to the
generic functions or somewhere, use static if:
// -----
static if (is(T == short) || is(T == int) || is(T == long)) {
// do anything
} else static if (is(T == real)) {
// ...
} else static if (is(T == char)) {
// ...
} else static if (is(T == string)) {
// ...
} else static if (is(T == int[])) {
// ...
} else {
// ...
}
Why not put in Phobos shorter design type switch:
// -----
type switch (T) {
case short, int, long:
// do anything
case real:
// ...
case char:
// ...
case string:
// ...
case int[]:
// ...
default:
// ...
}
This design has been implemented, for example, in Common Lisp
(typecase):

What do you think about this?
