If the behaviour is surprising, then the package writer wasn't
very skilled... A very large part of the skill needed to write a
module, is knowing how to design its interface so it becomes easy
to use, intuitive, and non-surprising.

On the other hand, *in*flexibility doesn't give any guarantee
against confusing situations. At least not as long as there is
enough flexibility in the language to actually allow you to do
anything more advanced than "Hello World".
And inflexibility will always make some situations horribly
daunting to get out of.
Powerful constructs like these can, in some cases, enable a
skilled package writer to design an API that reduces the amount
of boiler plate code needed for using the package.
If some authors write bad books, do you blame the English
language for allowing them to write such books, or do you
blame the writers for using English in a bad way?
