 15.3.11 Ruby Format Strings
 ---------------------------
 
    Ruby format strings are described in the documentation of the Ruby
 functions ‘format’ and ‘sprintf’, in
 <https://ruby-doc.org/core-2.7.1/Kernel.html#method-i-sprintf>.
 
    There are two kinds of format strings in Ruby:
    • Those that take a list of arguments without names.  They support
      argument reordering by use of the ‘%N$’ syntax.  Note that if one
      argument uses this syntax, all must use this syntax.
    • Those that take a hash table, containing named arguments.  The
      syntax is ‘%<NAME>’.  Note that ‘%{NAME}’ is equivalent to
      ‘%<NAME>s’.
