- codeStream reads three entries: 'code', 'codeInclude' (optional),
'codeOptions' (optional)
and uses those to generate library sources inside constant/codeStream/

Note the #{ #} syntax which is just a way of inputting strings with embedded

Note the \c \#{ ... \c \#} syntax is a 'verbatim' input mode that allows
inputting strings with embedded newlines.
Limitations:
- '~' symbol not allowed inside the code sections.
- probably some other limitations (uses string::expand which expands $, ~)
- probably some other limitations (uses string::expand which expands
\c \$ and \c ~ sequences)
