Okay, you've got a point with the R x C -> C case. However, I think mathematical convention and easy of use would be enough to justify the special case: v=vector(...) # n dimensional f(...)=... # f takes n numbers f(v) # behaves like f(*v) Note that we already do that for things like parametric_plot, derivatives, etc. So it sounds like we would just come down on opposite sides of this issue.
