The PITA is having to keep track of the indentation of each embedded chunk and
summing it for each level of indentation. This requires a fair amount of
bookkeeping that would not otherwise be necessary.
The original prototype simply replaced each embedded chunk with the text from
the chunk definition, all indenting information was lost. It worked for most
languages, but not Python.
In testing the program I used two languages, Python and J. I figured if I could
make both of them work I would not have any problem with anything else.
