Evaluate a nonlinear expression at a point

[Dan]

@Mitch_Phillipson

using JuMP
m = Model()

@variable(m,x)

@NLexpression(m,T,x^2)

#What is T(x=2)?

Continue with:

value(v -> Dict(x => 2.0)[v], T)

The first argument takes a JuMP variable name, and returns a value. So essentially the Dict can contain several variables and other ways are legit, as long as they return a value.
