Why do you think that f, which is a function from R^2-R^1, should not
naturally be able to take inputs that live in R^2?
I don't. But that's not the way that Python works, and the existing
implementation tries to make f(x, y) look like a Python function of
two variables. I would be fine

1. Recall your example:
sage: t = var('t')
sage: r=vector([t,t^2])
sage: f(x,y)=x^2+y
sage: f(r)
boom.
If we make f(r) work (as you propose), note that the following will
still not work, and can never ever be made
Note that we already do that for things like parametric_plot,
derivatives, etc.
And it's a continual pain in the ass. Telling the difference between
a list, tuple, sequence, iterator, vector, multiple arguments, etc...
in Python, it's just all so inconsistent. But it seems like the
