I found it too weird, especially if the goal of moving away from sh
scripting is to avoid gotchas caused by weird-and-magic syntax.

I've been playing a bit with the implementation here -- I basically
copied Penlight's path code and added some more command launchers
(sh.lines and sh.tokens, both return generators for "for"). I was in
the process of rewriting a large shell script I have but the process
is proving to be harder than I expected due to the amount of ugly
tricks caused by variable scoping I employed there. So I didn't get to
properly test much of the code I wrote, and therefore I ended up not
committing it yet.

for device, mountpoint, fstype in
fs.tokens.grep("-w","unionfs","/proc/mounts") do
   -- ...
end
