Failure in ParseArgumentList when using lambda filter on list of dictionaries

[astarche]

1. Description

Queries like ListOfDictionaries.Any(x => x.ContainsKey("key")) fail in ParseArgumentList.

Similar-but-different queries work fine, like ListOfDictionaries.Any(it.ContainsKey(\"test\")) and ListOfKeys.Any(x => x.Contains(\"test\")).

2. Exception

Exception message: ')' or ',' expected (at index 25)
