We compute a few verses of the Bottles of Beer song using Method paragraphs as both producers and consumers of data values.
First we define some quantities through givens and simple operations on them.
99 Bottles of Beer on the Wall -1 Take One Down Pass it Around SUM Bottles of Beer on the Wall Take One Down Pass it Around SUM Bottles of Beer on the Wall
Then we retrieve values following wiki-centric scoping rules and continue the calculation.

We can retrieve values from some data objects. For example, we can retrieve the first row of a dropped csv by citing the column header of the desired value.
We parametrize the last few verses of our song by citing a data for a Few or a Bunch of bottles. This is the fast way to get this tedious song finished.

Caution: We have yet to make the order of operations within methods reliably deterministic. If you see errors or unexpected values try refreshing the page.
