Awesome. May I additionally request that overlapping copy be mentioned in the
documentation

1: in std.algorithm.copy

something like

copy(a[5 .. 10], a[4 .. 9]); //valid
copy(a[4 .. 9], a[5 .. 10]); //invalid
copy(retro(a[5 .. 10]), retro(a[4 .. 9])); // invalid
copy(retro(a[4 .. 9]), retro(a[5 .. 10])); // valid

2: in Language / Arrays / Array Copying

just point the reader to std.algorithm.copy for overlapping copy
