Hi, all,
I want to create a "function" within a function, and return it as the value of
the latter function, something along the lines of:
def g(a,b,c):
var('x y')
f = a*x^2 + b*y + c
return f
This works, almost. I have to invoke the return value as a function returning
a function:
sage: f = g(1,2,3)
sage: f(0)
2*y + 3
sage: f(0)(1)
5
I can't treat it as a function of two variables:
sage: f(0,1)

It's not clear from the doc what should happen, but this is a bit of a surprise.
