Array!T is problematic as things stand -- e.g. you can't
foreach over
one.
Sure you can. Try it and rejoice:
void main()
{
import std.container, std.stdio;
Array!int a = make!(Array!int)(1,2,3,4);
//the rule is: if a can be sliced then slice it and use
that slice
foreach(v; a)
{
writeln(v);
}
}
The fact that foreach with a ref item or foreach with an index
doesn't work makes using them a lot more of a hassle than
built-in arrays though.
void main()
{
import std.container, std.stdio;
Array!int a = make!(Array!int)(1,2,3,4);
foreach(ref v; a)
{
v *= v; // no effect on a
}
writeln(a[]); // [1, 2, 3, 4]
foreach(v, i; a) // Error: cannot infer argument types
{
a[i] *= v;
}
}
