On solution to my problem is to tag my sample macro tiddler as a system
macro.
But this has the problems that its macros are now public and their names
must now be made unique.
I can do that by calling my macro as demo-for-this-and-that instead of just
macros (including helpers macros, which would clutter my main macro code).
and at the beginning of my how to tiddler I would add:
\define demo(foo:bar etc) <<demo-for-this-and-that foo etc>>
not very nice neither very practical but the best I could do so far.
