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?

Cheers.
