it's not a problem 'if' you 'remember' to use 'private'.

private 'within the module' is also not a problem, 'if' you 
'remember' that, when using private to encapsulate your class.

Again, other mainstream languages have already learn the lesson 
here, as to why public might not be a great 'default'.

knowledge is useful, I get it. so are safe defaults.

Thanks for clarifying this.
