well, not really, it just cannot auto deduce, the problem is, I don't know what to put in, I know that I can put in SwapStrategy.stable for the first one, but what about the Range, I don't know what to put in
E.g
int[] i = [ 1, 2 ];
i = i.remove( 1 );//able to automagically deduce

char[] c = [ 'a', 'b' ];
c = c.remove( 1 ); //unable to deduce what char[] is in range

The issue is that char[] is treated as an auto-decoding bi-directional range by Phobos, not an array.

To get Phobos to behave, you can use byCodeUnit:

import std.utf: byCodeUnit;

c = c.byCodeUnit.remove(1).source;

I see, so it means that only char is affected, gotcha

Well, char[] and wchar[]. dchar[] is treated as an array by Phobos. But calling byCodeUnit on a dchar array should work just like an array as well, so using it is the most generic solution.
