Cannot use value on Parameter Functions

[pulsipher]

JuMP.value is not implemented correctly for parameter functions, currently it errors.

using InfiniteOpt, Ipopt

model = InfiniteModel(Ipopt.Optimizer)
@infinite_parameter(model, s in [0, 1], num_supports = 4)
@variable(model, y, Infinite(s))
my_func(s) = 42
@parameter_function(model, pfunc == my_func(s))
@objective(model, Min, integral((y - pfunc)^2, s))
optimize!(model)
value(pfunc)

However, transcription_variable works:

julia> transcription_variable(pfunc)
4-element Vector{Float64}:
 42.0
 42.0
 42.0
 42.0
