   | The output of "set" includes more than just variables.  It also includes
   | shell functions.

But that's a clear standards violation - but to be clear, if posix mode

is turned on in bash, only the variables are output.

If posix mode is off, bash can do what it wants with the output.

 It could be perhaps
argued that including the functions is just an extension, but it isn't, as
the standard also specifies the format to be used for the output, and the way
functions are (effectively must be) output isn't in the required format.

Since POSIX doesn't apply unless posix mode is enabled, bash can output
functions as part of `set' output and use an output format that bash can
re-read as input.
