I know static arrays are not ranges but somehow they work with 'each'. With map, I need to slice as 'arr[]':

import std;

void main() {
  int[3] arr;

  arr.each!(e => e);    // Compiles
  // arr.map!(e => e);  // Fails to compile
  arr[].map!(e => e);   // Compiles
}

Why the inconsistency?

Phobos has dozens of random special cases throughout. I'd prefer if these were all removed, but right now there's just some functions that special case to allow it and others that don't.

Apparently each is one that does.

Special cases are always bad, inconsistency is a mental burden to the developers, and can even lead to serious but silent bugs when overlooked.

1) we should fix them as soon as we discover any of them
2) or at least doc such inconsistency with emphasize
