Sort of. You can't fetch a specific scope using dollar-sign expansion
unless you erase the local and/or global scope instance. Fish 2.7 has the
`set --show varname` command. This is primarily meant to help debug
perplexing behavior and in things like unit tests:
$ set -U varname universal value
$ set -g varname global is good
$ set -l varname locally handy
$ set --show varname
$varname: set in local scope, unexported, with 2 elements
$varname[1]: length=7 value=|locally|
$varname[2]: length=5 value=|handy|
$varname: set in global scope, unexported, with 3 elements
$varname[1]: length=6 value=|global|
$varname[2]: length=2 value=|is|
$varname[3]: length=4 value=|good|
$varname: set in universal scope, unexported, with 2 elements
$varname[1]: length=9 value=|universal|
$varname[2]: length=5 value=|value|
