Grasshopper 2 wish: stricter list-broadcasting

Hi there,

while GH2 is still in the making, I’d like to propose the following feature:

Right now in GH1, when a component is fed lists with different lengths (like list A and B in screenshot below), GH is doing its best to make that component work (ie it is extending shorter lists to match the longest list).

It would be awesome if this situation could throw an error message since more often than not, A and B are supposed to be of same length or be a scalar input.
This way it would be much easier to spot errors in our scripts.

Thank you!
