Formattable wrapper that uses `ostream` `operator<<` to format a type.

== Synopsis

Declared in `<bslfmt_streamed.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
template<class t_STREAMABLE>
class Streamed;
----

== Description

This class provides a wrapper to enable a streamable type to be used with `bsl::format` (and `std::format`) when no formatter specialization is provided (the type is not formattable). Note that it is possible to use this wrapper with types that have a formatter, if the compiler supports it we give a compilation warning directing the user to use the existing formatter instead of wrapping to use the streaming operator.
