Thanks for the sample and now I can access trivialFunc() from within a 
template file using:

<p tal:content="python:modules['Products.MyFunctions'].trivialFunc()"></p>

It works fine, just somewhat cumbersome. One way to simplify its usage 
is to use tal:define, like:

<p tal:define="func python:modules['Products.MyFunctions'].trivialFunc"
     tal:content="func()"></p>

But this would require using tal:define in every template file that 
could access the function.

Is there any other way to simplify the access to the function?
