Then you're willing to have different widgets. This is OK, just declare then
in your method and use them.

Nope, but if you want to use them as validators you have to remember how
scoping works and how decorators works.

@expose(...)
@error_handler(...)
@validate(...)
def function(...):
pass
is something like
def function(...):
pass
function = expose(error_handler(validate(function)))
so, if you had local variables inside your function, they won't be available
out of it. As you can see, decorators wraps functions, so ...
The easiest thing is to declare a global validator scheme -- of the widgets
themselves -- in your module and use them. You might try other things, but
always keep in mind what is happening behind the 'magic'.
