Alternative to "get" value from variable instead of capturing stdout

For example, if bb_getx() prints the result to stdout, have bb_getx-v() yield the same result in the variable $BB_RESULT.

my_x="$(bb_getx)"
bb_getx-v
my_x2="$BB_RESULT"
bb_expect "$my_x" "$my_x2" # should be same

Or bb_getx-v VARNAME [getx args ...] to put the value in VARNAME. Use printf -v "$VARNAME" '%s' "$VALUE".
