This is the right place to file an issue.

Your code is incorrect; it will find only top-level functions. Functions within an `if` statement will be nested inside an `ast.If` node. To find all functions in a file, you'll need to recurse into nested nodes. For example, you could use `ast.walk`, an `ast.NodeVisitor`, or manually check for nodes like `ast.If`. Which one is best depends on your needs. For example, the first two will also find methods in classes. The ast module documentation has more information.
