Decorators are actually a syntax hack remember. Everything you can do in a 
decorator you could do with python before since they work via nested scopes. 
It is easy to write wrapper methods and I use them for many purposes but not 
for type checking. 

Wrapper methods are very useful to take out common checking code. The checking 
of conditions does not really belong in the caller (the caller could forget), 
it does not really belong in the called function since that is not that 
functions purpose but putting it in a wrapper and having it wrap the called 
function sure gives a nice seperation and makes life simpler.
