Struct constructors

[Sean Eskapp]

In code like this:

import std.stdio;

struct foo
{
	int val;

	static immutable bar = foo(1);

	this(int val)
	{
		this.val = 50;
	}
}

void main()
{
	writeln(foo.bar.val);
}

The user-defined struct constructor is not called, because it's overridden by
a built-in constructor which treats it like an initializer list. Shouldn't
constructors in structs either generate errors/warnings, or work as they would
appear to?
