Pass name of function as a block

In Ruby it is possible to pass a function name instead of a block to a function expecting a block using &method in the last argument.

For example:

def blocky_fun(foo)
  bar = "hello #{foo}"
  yield(bar)
end

blocky_fun('blocky', &method(:puts))

The result of the above would be that the puts function will be called with “hello blocky" as the first argument.
