TypeError on parsing some valid expressions

[DRMacIver]

The following code:

import libcst

libcst.parse_module('() if 0 else(lambda:())')

Raises the following error:

Traceback (most recent call last):

This example is sensitive to whitespace. For example, inserting a space between the else and the opening bracket causes it to start working (or at least not crash, I've not checked if the parse is correct).

This is running with libcst 1.1.0 on Python 3.11.6
