Yes.
Because you didn't use a named argument.
These would have been valid declarations that would match that function
call:
void draw(Circle shape);
void draw(Rectangle shape);
In this example you didn't need named parameters.
Since the variable name of the calling body should be descriptive enough
to tell you that it is a circle/rectangle.
