well i can paste the original code lines here too but i dunno
its part of bigger sw, this code piece is not this i mean its its
singular file and acts as 'kws' function to resolve keywords

declare -a kws=( '' "$@" )
declare kwsi= kw id code takes _t

while [[ -v kws[++kwsi] ]] && kw=${kws[kwsi]} _t=$kwns$_S_
id=${KWS[$_t$_S_$kw]} code=${KWS[$_t$id]} takes=${KWS[$_t$id$_S_]} ;
do
 [[ $code ]] && kwseval "$code" "${kws[@]:kwsi:takes}"
 (( takes && kwsi += takes ))
done
