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()
```
