Supported arguments -// following the format string, such as strings, string_views, ints, -// floats, and bools, are automatically converted to strings during the -// substitution process. (See below for a full list of supported types.) -// -// `Substitute()` does not allow you to specify *how* to format a value, beyond -// the default conversion to string. For example, you cannot format an integer -// in hex. -// -// The format string uses positional identifiers indicated by a dollar sign ($) -// and single digit positional ids to indicate which substitution arguments to -// use at that location within the format string. -// -// A '$$' sequence in the format string causes a literal '$' character to be -// output. -// -// Example 1: -// std::string s = Substitute("$1 purchased $0 $2 for $$10.
