TypeScript type errors for op methods.

Problem

TypeScript compiler complains when using op as documented.

However, the library functions correctly.

Steps to reproduce

import * as aq from "arquero";

aq.from([{ a: 1 }, { a: 2 }])
  // Error: Type 'number' is not assignable to type 'string | TableExpr'. ts(2322)
  .rollup({ max: aq.op.sum("a") })
  .objects();

Expected Behavior

No compiler error

Thanks for pointing this out. This is a regression due to the more recent “fixes”. I’ll need to look into what support (if any) tsc has for defining overloaded functions from JSDoc.

Thanks! The types are indeed wrong here. I’ll look into fixing this soon.
