[Tutor] style question: when to "hide" variable, modules

[Alan Gauld]

> My question is, how far should one take these guidlines?

My response is, as far as you need and no further.
In other words if it would actually cause problems 
for clients to access those variables disguise them, 
but otherwise trust your fellow programmers not to 
be stupid.

Its the same principle as the recent discussion 
about private/public keywords etc. 

Comments and docstrings can help too.
