Issue ID: 14098
Summary: std.typecons.wrap should allow wrapping a struct
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P1
Component: Phobos

The current implementation of wrap only allows for other classes to be wrapped
into another interface. Structures are much more common in D so there is great
value in supporting the ability to wrap a struct into a specified interface.
This is similar to request #10404 but doesn't require a concrete type to be
produced.
For example:
interface iRange {
pure nothrow @nogc @property @safe int front();
void popFront();
pure nothrow @nogc @property @safe bool empty();
}
void main()
{
import std.algorithm;
import std.range;
// Create a range type.
auto squares = map!"a * a"(iota(10));
import std.typecons;
// Wrap it in an interface.
iRange squaresWrapped = squares.wrap!(iRange);
}
