> if anybody is using an alternative shell as a daily driver and getting considerably more out of it? I wrote my own. Originally motivated by the fact that bash doesn't handle `$VARWITHSPACES` correctly (if I want expansion, I can write `$@VARWITHSPACES`), but I get a surprising amount of mileage out of random features shoved into corners of the substitution syntax like: $ factor $@m/[0-9]+/$[(1<<15)-((2*$0)-1)]/q'1 2 3' 32767: 7 31 151 32765: 5 6553 32763: 3 67 163 (`$q''` produces a string, `$@m/regex/pat/` finds matches in it and expands `"pat"` for each with $0,$1,... set to captures, and $[expr] evaluates match expressions.)
