ObjectPattern instead of ObjectExpression inside BinaryExpression

[azz]

What version of TypeScript are you using?

2.4.0

What version of typescript-eslint-parser are you using?

ts-2.4 branch

What code were you trying to parse?

(a => ({})) + 1;

What did you expect to happen?

The {} should be an ObjectExpression.

What happened?

The {} is an ObjectPattern.

This is only an issue inside BinaryExpressions, and interestingly is not a problem with 1 + (a => ({}));.

See repro here.

Root cause seems to be this line:

typescript-eslint-parser/lib/convert.js

Line 616 in fb66f61

objectIsInAssignment = (nodeUtils.findChildOfKind(objectAssignNode.left, SyntaxKind.ObjectLiteralExpression, ast) === node);

I'd attempt to fix this but I'm don't know what that line was originally added for.

Thanks for the report. I can look into this on the weekend.
