[Error: std.format

This happens because doFormat is called recursively, once for each of the 
elements of the array. This means that there should never be any parsing for 
string elements, since there'll never be any 2nd argument to be formatted.

A possible fix (+patch) can be found at:

"Because the new doFormat takes the extra "bool parse" parameter, the fix is 
simple: invoke doFormat with parse set to false."
