can we some home magically to have BoundedVec like

BoundedVec<u8> = BoundedVec<0, 255>
BoundedVec<NonZeroU8> =  BoundedVec<1, 255>
BoundedVec<MyTraitImplmentingRange<42, 124>> = BoundedVec<42, 124>

So kind of make it composable with ranged numbers. Actually, on crates.io there are already several crates automating ranged numbers, not sure if any suits.

I'm not sure it's possible due to the limitations of rustc. I need to check on that to be sure.

It will allow to compose bounder numbers with bounded vector as possible range of values
