The docs couldn't possibly be more clear.

${map} provides the examples:

${map{a:b:c}{[$item]}}
${map{<- x-y-z}{($item)}}

So I ran them though -be:

root@haven:~# exim4 -be '${map{a:b:c}{[$item]}}'
[a]:[b]:[c]
root@haven:~# exim4 -be '${map{<- x-y-z}{($item)}}'
(x)-(y)-(z)
root@haven:~#

The output on its own explains exactly what it does without even having
to read the rest of the documentation.

The forall/forany documentation is equally clear and concise. I couldn't
write better documentation if you gave me an entire afternoon to come up
with it.
