noFunctionExpressionRule for generators

[anvish]

noFunctionExpressionRule should not react to function* () { yield 1; } since arrow functions cannot be generators.

@anvish
I cannot reproduce this.
What version of tslint are you using?
What exactly is your code?

[HamletDRC]

@anvish also, what version of TypeScript?

As far as I can tell, tslint 3.15.1 hardcordes an ES5 target for the compiler, so I don't see how tslint will even compile this code sample. Is the error really from the rule?

[anvish]

@HamletDRC
typescript 2.0.3
tslint 3.15.1
sample.tsx:

class A {
    do2(f: any) { }

    do1() {
        return this.do2(function* () { yield 1 })
    }
}

Message: [tslint] Use arrow function instead of function expression
After adding // tslint:disable:no-function-expression the warning disappears
