Wrong list. posh is a different shell than dash, so there's nothing
this list can do to change posh.

posh tries hard to limit itself to POSIX (harder than dash), and POSIX
does not yet define 'typeset', lacks 'declare', and does not require
'set' to list function bodies. Thus, as far as I can see, POSIX doesn't
require shells to be able to output function bodies. For posh to
provide this, they'd have to give you an extension beyond POSIX; but
that goes against the goals of posh. Sorry.
