respond not_*? missing methods

[sauloefo]

I want to any object be able to respond to any missing method called not_.*? as long as a method called .*? exists.

Example:

not_nil? as long as nil? method exists;
not_present? as long as present? method exists;
not_overdue? as long as overdue? method exists;

Why?

I prefer to read this:

if not_overdue? ...
# The code clearly tells me 

than this:

if !overdue? ...
# I have to "compile" the code in my mind to understand what that ! means
