Kia ora,
I'm working with a shell script that does this:
```
for i in $(seq 1 9)
do
tags=$((1 << ($i - 1)))
...
end
```
Source: https://github.com/riverwm/river/blob/master/example/init
It's shifting the bits to produce a 32 character string that's used to tag
windows for a window manager. The window manager view changes depending on
windows & these 32 characters for each of them. They use the bitwise operator
to perform binary magic that's beyond me honestly.
Anyway, I'm wondering if there's an equivalent fish `math` function or operator
to perform bitwise shifts.
Ngā mihi,
Aiden
