[Modules] aliases with square brackets in tcsh and modules 4.8.0

[Andreas F. <af...@me...>]

Hello,

we are currently trying to migrate from Modules 3.2.12 to 4.8.0.
Environment is RedHat 8 & 9, shell is tcsh.
We do not have the option to switch to anything else currently.

I need to have something like

> set osrel 80
> set-alias mycommand "bsub -R \"select[type==X64LIN && osrel==$osrel]\"
myapp"

However, no matter what kind of escaping and quoting I apply (or none at
all), I always end up with tcsh complaining:

alias: No match.

It seems the square brackets end up unescaped and unquoted in the tcsh
alias command, no matter what I try. Resulting in a failing shell pattern
match which is not what I want of course.

I tried:
[...]
\[...\]
{[...]}
{\[...\]}
{\\[...\\]}
{\\\[...\\\]}
"[...]"
"\[...\]"
"\\[...\\]"
"\\\[...\\\]"
and probably some more, all without success.

Is there a way to get this working in 4.8.0? Is it a bug that's maybe fixed
in newer versions (which I currently cannot test unfortunately)?

Any help would be greatly appreciated.

Andreas
