When assigning a lambda to a variable right after an if statement, the parser seems to understand that a ternary expression is happening when in fact it is not.

### Steps to reproduce

Put the code bellow on a script on an empty project
```gdscript
func test():
	var v
	if true: v = (func(): test())
	if true: v = (func(): test())
	if true: v = (func(): test())

	if true: v = func(): test()
	if true: v = func(): test()
```

### Minimal reproduction project

N/A
if (builtin_types.is_empty()) {
		for (int i = 1; i < Variant::VARIANT_MAX; i++) {
			builtin_types[Variant::get_type_name((Variant::Type)i)] = (Variant::Type)i;
		}
	}
	if (builtin_types.has(p_type)) {
		return builtin_types[p_type];
	}
	return Variant::VARIANT_MAX;
}
