[TriZPUG] pylint magic

I have some code, a function invocation, which looks like:


pylint flags that statement with the message:

"Used * or ** magic"

Is using tuple or dict expansion in a function argument really 
considered "magic" in a community sense?

Is this a PEP violation which got by me? Or just a pylint bias?

To me, the statement is just Pythonic elegance. If I already have a 
tuple appropriately ordered to match a function's parameter signature, 
why would I want to go through tuple unpacking into a bunch of new 
identifiers just to satisfy some overreaching meta-explicitness. This 
seems to me like a hobgoblin of little minds rather than enhanced 

What am I blind to here? The function being called is in the same module 
and has an explicit parameter signature. With doctests. And passes pep8 
and pyflakes.

Please discuss amongst yourselves for my edification.
