nimforum mirror - Associating a constant with a concept?

I'd like to associate a type-wide constant with a concept in some of my concept implementations. Currently I'm doing this:

type AddMonoid* = concept x, y, type T
  zero(T) is T

func zero*(x: typedesc[float]): float = 0.0
func zero*(x: typedesc[int]): int = 0

Then in practice to access the zero value for (say) a float:

echo zero(float)

Is there a more idiomatic way of going about this?
