[erlang-questions] Improve $handle_undefined_function

[Loïc Hoguin]

You missed the humor.

No one forces me, or anyone else, to use it. Indeed we can recommend 
people not use it and tell people to avoid using libraries that are 
using it, and if they still do tell them to *really* be careful about 
it. All this not because we think the *feature* is bad, but because the 
*implementation* can easily lead to user error.
