Common patterns
- ~って言う: to say that ~
- ~って聞いた: I heard that ~

The quotation use (sense 1) is essentially a casual form of と in reported speech. The hearsay use (sense 2) adds a nuance of secondhand information, often with よ or さ. The topic use (sense 3) parallels は but often carries a questioning or definitional tone.
