[Question] Is it possible to modify how pyinvoke casts/reads input parameters?

[red8888]

I want to automatically cast string params passed to my @tasks with a value of "null" or "Null" to None. Is this possible?

I can add this logic myself of course, but wondering if pyinvoke has any features for this.

I thought about overloading str as well, but maybe there is a feature of pyinvoke that provides hooks into tasks so I can write a sort of middle man function that is executed against the params that does custom stuff?
