[Python-ideas] Decorators for variables

[Matthias welp]

> Function decorators

There are decorators that return a callable that not calls the function
that was given as an argument, but also do some other things, and therefore
change the behaviour of that function.

If possible, yes. So that there is a standardized way to access changing
variables, or to put limits on the content of the variable, similar to the
@accepts and @produces decorators that are seen here (

)
