I can't see disallowing default arguments as being a good thing. For example,
instead of,
void foo(int a, int b = 2)
{
...
}
surely I can just put instead
void foo(int a, int b)
{
...
}
void foo(int a)
{
foo(a, 2);
}
... and surely I can do something similar for function pointers and delegates.
So, I can still have default arguments in effect, I just have to work more as a
programmer, using a less friendly and easy-to-understand syntax. That doesn't
really seem like a good way to operate unless there's an extreme level of
complication in getting the compiler to handle the situation.
