:cache header argument controls the use of in-buffer caching of
the results of evaluating code blocks. It can be used to avoid re-evaluating
unchanged code blocks. This header argument can have one of two
- The default. No caching takes place, and the code block will be evaluated every time it is called.
Every time the code block is run a SHA1 hash of the code and arguments
passed to the block will be generated. This hash is packed into the
