block-scoped-var behaves in a weird way

[mgol]

The following code:

/* eslint block-scoped-var: 2, no-undef: 0, strict: 0 */
function f() {
    for (let i = 1; i < l; i++) {
        expect(i).toBeBiggerThan(0);
    }
}

with ESLint from master returns this:

test.js
  3:20  warning  "i" used outside of binding context       block-scoped-var
  3:24  warning  "l" used outside of binding context       block-scoped-var
  3:27  warning  "i" used outside of binding context       block-scoped-var
  4:8   warning  "expect" used outside of binding context  block-scoped-var
  4:15  warning  "i" used outside of binding context       block-scoped-var

First of all, i is within its context here. Secondly, expect is used exactly once so it's weird there can be any context-related error here...

Yeah, looks like block-scoped-var doesn't acknowledge declarations within for and for-in inits. I'll take a look at it.

Thanks. Is the expect warning caused by the same issue or is it a separate one?

That's not an issue. expect was never declared, so it's a reference error. Same thing with l.
