This is a great idea. I tried to define another state like this
dx[5] = :(1.0)
But I get the following error:
MethodError: Cannot `convert` an object of type Float64 to an object of type Expr
This may have arisen from a call to the constructor Expr(...),
since type constructors fall back to convert methods.
Stacktrace:
[1] setindex!(::Array{Expr,1}, ::Float64, ::Int64) at ./array.jl:578
[2] include_string(::String, ::String) at ./loading.jl:522
I tried e.g. converting to an Abstract type
dx[5] = :(convert(Real, 1.0))
and this if fine, but then when I do configure I get
julia> configure!(n;(:Nck=>[50]),(:finalTimeDV=>false), (:tf=>tplan))
Unrecognized function "convert" used in nonlinear expression.

So I am not sure how to implement this.
