[nem-en] closures in constructors

[Don Reba]

Ran into this bug. In the example below, a function nested inside a constructor attempts to assign a class member, but fails, since it is part of a closure. If this is done inside the constructor itself, and not inside a nested function, everything is fine.


class C
{
	i : int;
	public this()
	{
		def f()
		{
			// assignment of a class member
			// error: assignment to immutable field is allowed only
			// inside code, which is executed inside constructor,
			// but this field access is done through closure
			i = 3;
			// creation of a closure
			mutable j;
			[].Iter(fun (_) { j = 3 });
		}
		f();
	}
}
