Solution to a minor puzzle that came up during today's lesson with Ella:
some sandboxes were showing the address of text results, while others
were showing their contents. It took a while to realize that the
distinction lay in whether the sandbox was saving the results in a text
variable:
new [abc]
=> <some address>
x:text <- new [abc]
=> abc
It took *much* longer to realize why I couldn't make the first case work
like the second. Eventually I realized why: recipes were reclaiming
their results if they weren't 'escaping' -- that is, being saved in a
variable in the caller so they could be used later.
Any solution to this would be a hack, so I'm going to just leave it
alone. Type abbreviations should help minimize the extra typing needed
to get sandboxes to show text contents.
