Ironically, I just came across the relevance of prefixes in:

"FWIW, I would like to see this debate resolved through the use of
recently introduced mechanisms.  A folder full of Python scripts is
equivalent to a Python module containing only functions, therefore, we
should provide a simple UI for site developers to write persistent
modules.  Then we should provide an easy way to call persistent modules
from templates; the new prefix stuff should be pretty effective for that."

Unfortunately, I can't digest the prefixes and believe that scripters will
easily take it.

What's exactly wrong with a standard function call using a path(s) as a
parameter:

<span tal:replace="fmt.truncate(container/path/to/var, 10, more='...')">
