This isn't a good feature, IMO. C# handles this much more
conveniently with just as much optimization/debugging benefit
(arguably more so, because it catches NaN issues at
compile-time). In C#:
class Foo
{
float x; // defaults to 0.0f
void bar()
{
float y; // doesn't default
y ++; // ERROR: use of unassigned local
float z = 0.0f;
z ++; // OKAY
}
}
This is the same behavior for any local variable, so where in D
you need to explicitly set variables to 'void' to avoid
assignment costs, C# automatically benefits and catches your NaN
mistakes before runtime.
Sorry, I'm not trying to derail this thread. I just think D's has
other, much better advertising points that this one.
