Hi,

If there a way to write the function 'x' into one function, not 2
overloads.
I tried auto/const/ref mindlessly :D, also remembered 'inout', but
obviously those weren't solve the problem.
Your original code is an odd situation -- you want to return by ref if
it's mutable, but not if it's const?
Why not return by ref always, and just forward the constancy? This is
what inout is made to do:
ref inout(int) x() inout { return array[0]; }
(This is going to be a swizzling 'system' that mimics GLSL, later I will
make a template that takes 'x'as a template parameter, just wondering
that the support for const and non-cons can be done easier.)
If you want to differ behavior by const, but write one function, you can
use a `this` template parameter. But without seeing your real use case,
you might end up writing the same amount of code.
