} Ah, it's about prediction
The most obvious/foolproof thing would be to use a subshell:
newPWD=$(cd -q $where >&/dev/null && pwd)
Next would be globbing:
# Assumes last component of $cdpath is "."
cdWD=( $^cdpath/$where(N[1]) )
newPWD=${cdWD:A}
Note this is exactly what :A is supposed to be for, but it gives the
wrong result if CHASE_LINKS or CHASE_DOTS is set, so you may need the
new :P modifier, or the :a modifier instead. [[ -o ... ]] tests left
as an exercise.
