[General] Component-wise dynamics

[ocots]

Is it what we want—to forbid defining dynamics component-wise using the dot notation?

julia> ocp = @def begin
           t ∈ [t0, tf], time
           x = (q, v) ∈ R², state
           u ∈ R, control

           x(t0) == x0
           x(tf) == xf

           q̇(t) == v(t)
           ∂(v)(t) == u(t)

           0.5∫( u(t)^2 ) → min
       end
ERROR: Control Toolbox Error

❌ Error: CTBase.Exceptions.ParsingError, 
Line 6: q̇(t) == v(t)
