Reading the type_value documentation from Boost Program options feels like:

    typed_value * composing();     Specifies that the value is composing. See the 'is_composing' method for explanation.

And the documentation of is_composing:

    bool is_composing() const;

Not sure if I know more what this function is supposed to do now.

I agree that this seems somewhat unhelpful. FWIW a quick look elsewhere found https://www.boost.org/doc/libs/1_68_0/doc/html/program_options/tutorial.html... which describes that option in more detail -- specifically that it's whether repeated parameters are merged or just replace the older value.

Also, I think this module/documentation should take a s/method/function/g.

"Method" is the more common name for a method within a class.
