As a matter of example : this scripts "rewrites" its final command
depending on optional arguments. Its purpose is to restore select parts
of the environment variables, uid/gid and working directory, that were
saved in a directory at some point in the past.

Maybe it is pushing execline a bit too far but I didn't fell like coding
it in C (which I do no master).

Remember that once an execlineb script has been parsed, it's just a
command line, no more, no less. So your example script can just be
written as:
#!execline
define url example.com
s6-tcpclient $url 80
foreground { fdmove 1 7 echo -en "..." }
fdmove 0 6 cat
No second execlineb invocation necessary at all. No quoting
nightmares.
Ooooooh, you are right!
It’s even more elegant than I thought!
Nice.
