How to list functions?

How to list functions?

[Alexander Huemer]

Hi,

posh has support for functions.

$ f() { echo foo; }
$ f
foo
$ 

Unfortunately I am unable to list the defined functions.
I tried `typeset`, `declare` and `set` without success in posh 0.10.2 on 
Debain Wheezy.
Any hints very welcome.
Thanks in advance.

Kind regards,
-Alex

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.

posh tries hard to limit itself to POSIX (which does not yet define
'typeset', lacks 'declare', and where 'set' does not list function
bodies).  As far as I can see, POSIX doesn't require shells to be able
