Furthermore, post arguments are useful for commands with two mandatory
arguments where you want to have the first to be what is entered in the
main work area. For instance memoir's epigraph command
(\epigraph{<text>}{<source>}). It would be rather odd if the source
would be in the main work area and you'd would have to type the text in
an inset. Actually, all of the current usages of post in the LyX
distribution are of this kind.
