This should be allowed but is not:

for (() => { this in a };;);

Slight correction:

This is currently allowed:

for (() => {(this in a)};;);

And this should be allowed but currently isn’t:

for (() => {this in a};;);

Correct. Copy/paste error. I will edit my original message to avoid confusion.
