I haven't formed an opinion on what the "right" behavior should be...
without examples, it seems as good as anything.
my analogy for why it's "right" already is
set -g v a
function f
echo $v
end
function g
set -l v b
f
end
#g outputs a
#therefore functions are similar to commands
#But "globals" really are not quite the same as lexical scopes
#now, it's a bit odd how differently functions and
#commands are treated...
function g1
set -lx v b
f
end
function g2
set -lx v b
sh -c 'echo $v'
end
#g1 outputs a; g2 outputs b
Maybe that oddness is part of the function of a shell. Maybe commingling
shell-programming-variables, and exported-variables, is too confusing
always. The proposed `cd -l` will probably have more consistent
semantics: implicitly exported to both functions and external commands;
dynamically scoped, lasting until the end of the function, I guess.

yes, this is interesting although it does change XDG_CONFIG_HOME for
other apps as well, I expect... but good to know! I will consider it.
build failures:
I needed to install gettext (error about msgfmt command missing) (this
dependency was not mentioned in INSTALL).
Installing to prefix $PWD/inst,
...
for i in fish set_color mimedb fish_pager fishd fish_indent
xsel-0.9.6/xsel ; do\
/usr/bin/install -c -m 755 $i
/Users/me/modified/fish/inst/bin ; \
done;
/usr/bin/install: cannot stat `xsel-0.9.6/xsel': No such file or directory
make: *** [install-force] Error 1
What? I tried creating the directory
/Users/me/modified/fish/inst/bin/xsel-0.9.6 , and re-installing, and it
errored in the same place.
Oh wait, I need to install the xsel package (or explicitly give
--without-xsel). This message at the end of 'make' is not quite right:
"
Failed to build xsel - either add the required dependencies or use
'./configure --without-xsel' to disable it.
fish has now been built.
Use 'make install' to install fish.
"
because the last two lines obscure that the first one I quoted is in
fact a fatal error that will prevent installation.
Also it seems I need libx11-dev, (maybe libxext-dev, maybe libice-dev...
the latter guesses from xsel's dependencies, that didn't seem to help
anything?) Do you have any idea where X11/StringDefs.h and
X11/Intrinsic.h are to be found? Meanwhile I'll disable xsel.
by the way, I ran into another crash -- (presumably all
fish-stack-traces are bugs that should at least give some other error
message?). (but this one is fixed in darcs (I tested) so I won't
mention it [1])
Okay, now testing
also --help. `cd --help` coloring is fixed now, but not `pushd --help`
and possibly a bunch of others.
also, on ubuntu, 'bash' tells you if you try to use an uninstalled
command, what package to get it from. Of course this is the distro's
doing... but, I wonder what sort of support it needs from fish. Just
using "bash -i -c 'svn'" is enough to trigger
"
The program 'svn' is currently not installed. You can install it by typing:
sudo apt-get install subversion
bash: svn: command not found
"
which is useful information, though I guess there's a better command to
get it from, that I just don't know about...

otherwise-deleted text
When fish doesn't have permission to access $HOME or related
variables... it gets very confused.
(I'm using a Sudo version 1.6.8p12 that doesn't clean up the environment
very much, so it inadvertantly tried to run $SHELL (fish) as a different
user but with my $HOME)
]sudo -u east -s
