Accesing Controller Data from module

[eluser]Uto[/eluser]
Is it possible to access to properties of the calling controller from a module other than passing it as parameters?

I mean something like:

Code:

$this->parent->propertyname

I have a module that was able to load all data needed from constructor itself, no needing any parameters, and it's widely used in the application. But now, under some circunstances, that happen a 0.5% of the times it's used, it may need to get a property from the "parent" controller, and changing it all over the code is quite risky.
