The default could be picked for whole blocks. So along with
i = j [*] 2
n = n [+] i
create new syntax to declare what operators mean inside a block:
option math=integer do
i = j * 2
n = n + i
I am not thrilled with this, but I've considered a similar facility to allow code to opt-in to making the ".." operator be utf8-safe.
