Thanks Jakob! I did try toChars but I couldn't quite figure out
a syntax of calling it that the compiler was happy with. From
memory I tried things along the lines of:
string v = toChars!(16,char,LetterCase.lower)(i);
to convert an integer to Hex for example, but the compiler wasn't
happy with it. How would I convert an int to a string using this?
