Cannot combine array indexing with minus

[Colossus]

Just tried writing a query like blah(wordidxs[1] - 3) :- .... , but cannot combine - with array indexing

Workaround: create intermediate tables

@feiranwang I think we did arbitrary expression here but maybe this is a parse error?

Yes, this looks like a parse error. I'm looking into it.
