Removing an invalid path from PATH

[SeSodesa]

I have a little problem with having added an apparently "invalid" path into the global PATH variable and now being unable to remove it because of the invalidity. To be more specific, here is the issue:

>> set --show PATH
$PATH: set in global scope, exported, a path variable with 14 elements
$PATH[1]: |/home/santtu/.cargo/bin|
$PATH[2]: |/home/santtu/.local/bin|
$PATH[3]: |/usr/local/sbin|
$PATH[4]: |/usr/local/bin|
$PATH[5]: |/usr/sbin|
$PATH[6]: |/usr/bin|
$PATH[7]: |/sbin|
$PATH[8]: |/bin|
$PATH[9]: |/usr/games|
$PATH[10]: |/usr/local/games|
$PATH[11]: |/usr/local/julia/1.7.2/bin|
$PATH[12]: |/usr/local/texlive/2022/bin/x86_64-linux|
$PATH[13]: |/snap/bin|
$PATH[14]: |/snap/bin|

>> set --erase --universal $PATH[11]
set: /usr/local/julia/1.7.2/bin: invalid variable name. See `help identifiers`

(Type 'help set' for related documentation)

I am guessing that it is the purely numeric folder name 1.7.2 in $PATH[11] that is causing this problem. My guess is that a similar issue might then occur with $PATH[12] as well.

What are my options regarding the removal of this particular entry? Should I just run something like

set -U PATH paths I want to maintain

or is there another alternative where fish just does not notice that there is something invalid in the thing it is trying to read and therefore just does what I ask it to?

set --erase --universal $PATH[11]

try

set --erase --universal PATH[11]

Ah, I think that was it. I needed to reference the list and not the thing it contains, of course.
