you're talking about this construct:
int[] arr;
void foo(int[], params) {}  => arr.foo(params);

This should not be considered a hack but rather should be a feature 
extended for all types. see extension methods in C#.

I also think that arrays (containers) must be distinct from 
slices/ranges (views).
