[GTALUG] Go fish?

Wondering if anyone here has experience with the fish shell <https://fishshell.com/>, which I discovered as it is the default in Bazzite Linux. Non-POSIX-compliant by design, it appears to be far more advanced in tab-completion and inline syntax checking than bash. ("You'll never write esac again", they say...) Has anyone tried it? Is it anyone's daily driver? Thanks! - Evan
