Why not simply allow programmer to declare auto variable at
function call side like in `foreach`?
E.g.
```d
void foo(int width, int height){...} //function definition
foo(width = 2, height = 3); // function call
```
the equal sign cant be used because D behaves like this
int width, height;
foo(width = 5, height = 10); // 5
// 10
width.writeln; // 5
height.writeln; // 10
void foo(int width, int height)
{
width.writeln;
height.writeln;
}
and in python
def foo(width, height):
print(width)
print(height)
width = 0
height = 0
foo(width = 5, height = 10) # 5
# 10
print(width) # 0
print(height) # 0
