Currently, the following works:

var('t')
parametric_plot((t,t^2), 0, 2)

since things are just passed to plot, and plot accepts a variable range 
as just two arguments, rather insisting that they be in a tuple.

However, the following doesn't work:

parametric_plot((t,t^2,t^3), 0, 2)

since parametric_plot3d insists that its variable ranges be specified as 
tuples, like (0, 2).

In a refactoring of some of the plotting code on #7008, I made it so 
that the first example is deprecated, so now someone would instead have 
to do:

parametric_plot((t,t^2), (0,2))

or

parametric_plot((t,t^2), (t,0,2))

Is there anyone opposed to this deprecation?


Thanks,

Jason
