Part of #43927. Generator expressions of the form (value for x in data if condition) are clearer, more concise and more pythonic than map() and filter() in cases where the appropriate value selector or predicate would need to be defined as a lambda expression. Furthermore, where those generators would be passed to list(), set() or dict(), comprehensions are even more concise.
