I can appreciate the sentiment, but are you asking me to implement some/all of the functionality of the double-paren arith expansion, partially duplicating the functionality of the test/[ command, simply because (( a & b )) is more bash-ful than [ a -bwa b ]? I'm not trying to bake-in any sort of assumption here, in fact, I'm just trying to get clarification.
