Broadcast inside of `@mtkmodel` macro causes precompilation failures when put into a package

Ok, thanks for the advice.

So I guess somethign like

initial_conditions = reduce(vcat,[collect(mass.s .=> [0.0, 1.0, 1.0]), collect(mass.v .=> [1.0, 1.0, 0.0])])

is the way to go isn’t it ? When multiple vectors have first to be collected, then gathered together through reduce
