also look very intuitive. I looked at std.algorithm.mutation and did
not find anything for this. I see only simple remove option.
The D equivalent is this:
array = array[0..$ - 1];
array = array[1..$];
Arguably just as intuitive.
I think there is a difference -- Swift arrays are not slices, so Array
is not the same type as ArraySlice.
I believe Array.removeFirst is O(n). I think it also returns the element
removed.
I also believe that it will affect any slices of the array, unlike D code.
Swift also has Array.dropFirst(n), which does what the D slice does (and
returns an ArraySlice). Arrays also support slicing like D does, though
with different index range notation.
Not 100% sure, the docs are not super clear on this.
I'm quite glad D stuck with the same type for arrays and array slices.
