Bug 19835 – Make std.algorithm.mutation.copy accept static arrays as sources

import std.algorithm.mutation; void main() { ubyte[2] a = [ 1, 5 ]; ubyte[] buf; buf.length = 40; auto rem = a.copy(buf); // worked on 2.085.1, broken in 2.086 } Error message: onlineapp.d(10): Error: template std.algorithm.mutation.copy cannot deduce function from argument types !()(ubyte[2], ubyte[]), candidates are: /dlang/dmd-beta/linux/bin64/../../src/phobos/std/algorithm/mutation.d(368): std.algorithm.mutation.copy(SourceRange, TargetRange)(SourceRange source, TargetRange target) if (isInputRange!SourceRange && isOutputRange!(TargetRange, ElementType!SourceRange))

@shove70 created dlang/phobos pull request #7070 "Fix issue 19835 - std.algorithm.mutation.copy static array source arg…" fixing this issue: - Fix issue 19835 - std.algorithm.mutation.copy static array source argument broken https://github.com/dlang/phobos/pull/7070

The `std.algorithm.*` packages are for working on input ranges, which static arrays are not. I think accepting them isn't a bad idea but I'm going to relabel this from "bug" to "enhancement" and change the title to reflect this.

Thanks!
