Aliasing

Create an alias with using, for:

• Member variable alias
  using var x = data[0]
using Int y = data[1]
using T z = data[2]
  • Not quite possible in C++.
    • With T& z = data[2] unfortunately memory is created for the reference (the pointer).
    • And this indeed is necessary here, because the reference could be assigned differently in the constructor, so it is not possible to optimize it away.
• Member function alias
  • using func f(String) = g(String) to alias the function g(String).
  • using func f = g to alias all overloads of the function g.
• Type alias in a class
  • using InParameterType = const StringView
    (no typedef)
