In bash a variable valuable can be accessed with the dollar sign $varname. That gets value of a local variable and fall backs to environment variable.
In closh it is currently done with (str varname) and (getenv "varname") which can become quite chatty. I am considering whether we should expand variable value with dollar sign too. Should we also fall back to environment variable?
With the fall back $varname could become something like:
Another thing is expansion in strings: "$a/${b}". Here are am leaning against it since it gets complicated with escaping rules.
Workaround can be to used some string interpolation library like strint/<< or cuerdas istr: (istr "~{a}/~{b}"). But maybe we could try to create a library to implement this in a bash compatible way like ($ "$a/${b}").
