*** What happens to the results?
Org-babel provides two fundamentally different modes for capturing
the results of code evaluation, specified by the :results header

*** Arguments to source code blocks
In addition to evaluation of code blocks, org-babel allows them to
be parameterised (i.e. have arguments). Thus source code blocks
now have the status of *functions*.
*** Internals
For those interested in hacking org-babel, it's worth going
through what actually happened there:
***** org-babel-execute-src
1. parses source block info (recognises language, looks for
arguments (there aren't any))
2. calls
***** org-babel-execute:LANG
1. resolves referenced variables (there aren't any)
2. assigns any referenced variables and evaluates body
***** org-babel-LANG-evaluate
Returns a string corresponding to either output or value of block.
