I have a const(char)[] string being passed in as a parameter (can't change
that) and I want to create a duplicate that is not const.

I tried all manner of things that would make sense to dispose of the constness
of it.  It's looking though that I will have to actually loop through and cast
every freaking character?

void myfunc(const(char)[] sin){
  char[] sout = cast(char[]) sin; // nope
  char[] sout = cast(char[]) sin.dup; // nope
  char[] sout = (cast(char[]) sin).dup; // nope

What's the trick?

I just use ...

    char[] sout = sin.dup;

What version of D are you trying this with?
