Hello folks,
Hope everyone is doing fine. Considering the following code, in
the first condition, I am extracting the type Point from the
slice Point[]. I searched in the std.traits, and could not find
a neater solution something like ElementTypeOf!T. Is there any
neater solution for it? Thanks in advance.
```d
static if (isArray!VecPoint){
VecPoint dummy;
alias Point = typeof(dummy[0]);
} else static if (isRandomAccessRange!VecPoint){
alias ASeq2 = TemplateArgsOf!VecPoint;
alias Point = ASeq2[0];
} else
static assert(0, typeof(VecPoint).stringof ~ " type is
not supported");
```

This one's not in std.traits:
```d
import std.range : ElementType;
struct Point { int x, y; }
unittest {
Point[] points;
assert(is(ElementType!(typeof(points)) == Point));
}
```
