Boo (the second-greatest programming language from Brazil) does it like this:

result = [1, 2, 3].Find() do (item as int):
      return item > 1

The rule is that if the last argument of a function is a function,
then it can be defined afterwards with a do-block.

(Boo looks like Python, but underneath it's a statically-typed
language with local type inference, which is a popular choice these
days)
