How to get the current paragraph as input range to function

I have looked in vain in the documentation (i.e. probably not
looked for the right keyword in the right places) to find a way to
have a function use the current -- blank-line delimited --
paragraph as its input range. Is there any way to do that other
than first visually selecting the paragraph?
