-The `fmt()` function takes the format string, and expects a single numerical

-The `fmt2()` function takes the format string, and expects two string arguments.
-It is not necessarily an error if either or both of the arguments are numbers,

-specifiers, with the requisite number of numerical or string arguments.  I know
-how to do this with the `...`/`arg`/`unpack(arg)` table specification in Lua,
-but numeric specifiers need to convert any strings passed to the function to
-numeric values instead of strings.  This is the challenging part, but should be
