Right, I am sorry, thank you for spotting it.
There's the moderate need for a different kind of cast, for collections
(arrays).
At the moment you can do:
import d.func: map, putr, array, xcast;
import std.conv: toInt;
import d.templates: ArrayType1;
void some_function(int[] x) {
putr(typeid(typeof(x)), " ", x);
}
void main() {
short[] x = [cast(short)10_000, 5_000, 100, 6_000, 50, 950];
some_function(map((ArrayType1!(typeof(x)) s){return cast(int)s;}, x[0 ..
4]));
// or less DRY:
some_function(map((short s){return cast(int)s;}, x[0 .. 4]));
// better:
some_function(array(xcast!(int)(x[0 .. 4])));
}
The last version with array and xcast may be acceptable. The advantage of using
it is that the ranges 0..4 can be variables.
Built-in types aren't constructors-functions, so you can't do something like
this:
some_function(map(&int, x[0 .. 4]));
