expressions (treating them like lambda functions rather than like
expressions)

Comment:
Played with some examples and can see that the examples below act like
lambda functions now (regardless of variable name or variable order or
function format - all plots came out the same as expected). Hope that
helps speed up the review (someone will still have to do the code review)
{{{
var('x y v w')
def f(x,y):
return x*sin(y)
g(x,y)=x*sin(y)
plot3d(f, (x,0,3), (y,-6,6), viewer='tachyon')
plot3d(f, (y,0,3), (x,-6,6), viewer='tachyon')
plot3d(f, (v,0,3), (w,-6,6), viewer='tachyon')
plot3d(g, (x,0,3), (y,-6,6), viewer='tachyon')
plot3d(g, (y,0,3), (x,-6,6), viewer='tachyon')
plot3d(g, (v,0,3), (w,-6,6), viewer='tachyon')
}}}
