As a non ruby dev... This "block" malarkey has always seen slightly deranged to me. You know what would be even nicer syntax? Proper higher order functions!

Haskellish syntax example:

    execute f = f "test response"

    perform = execute

    perform print

Your code is very limited. Blocks allow you to return any type of object or to have any kind of side effects, the result is not limited to be an IO monad. Also in Haskell you can't use variable number of arguments and the syntax is very different (curry by default of first argument), so no way to translate haskell style to ruby.

Your proposal ignores that Ruby blocks support `break`, `next` (continue), `return` and exceptions.

    def execute(f)
      f.call "test response"
    end

    perform = TOPLEVEL_BINDING.method(:execute)

    perform.call Kernel.method(:puts)
