Multiple assignment target + comprehension causes code to disappear

[lars447]

Hi,
I've been playing around with your tool and noticed a potential issue.
When in adjacent lines the multiple assignment transformation is performed followed by a comprehension tranformation, the multiple assignments are correctly merged into a single line multi assignment. However, the code that would have been transformed into the comprehension simply dissapears (messing up the indentation in the process).

Example

def solve(self):
    provider = Provider(self._package, self._pool, self._io)
    locked = {}
    for package in self._locked.packages:
        locked[package.name] = package
    return locked

Expected Outcome

def solve(self):
    provider, locked = Provider(self._package, self._pool, self._io), {package.name: package for package in self._locked.packages}
    return locked

Actual Outcome

def solve(self):
    provider , locked  = Provider(self._package, self._pool, self._io), {}
        return locked

Best,
Lars
