array.sh: REFACTOR: All functions that are value getters (get, tryget, find, length) set a variable now. This is similar to the shell's builtin "read". This is to behave better for errors: no subshells invoked: because $(foo bar) would invoke a subshell and prohibit proper fatal exits. BUGS: Name clases on variables. Check that _varname does not clash with a declared local.
