This is an interesting discussion topic. Scala is widely regarded as

Marketing. Scala is most often contrasted with Java, so since it has
lambdas, higher-order functions, and free functions, it is "more
functional" than Java.
1) It has pattern matching, lazy stream lists similar to Haskell
lists, its standard library is rather functional oriented, its has
better type inference,
Not a functional thing.
You used this point as one of four when you described what's needed to
categorize a language as functional at one of your talks with Herb and
Scott posted here recently. The other three were: lambdas, immutability
and purity. Which would mean that Scala fulfills, at least, two of your
requirements.
Type inference was not one of the things I mentioned.
