I think it would be very cool if one could do e.g.

sort((1,4,5,3))

and it would return a sorted tuple blazing fast without allocs. There are packages in the ecosystem like
SortingNetworks.jl that can do this, but they cannot overload Base.sort without piracy. So if sort is used inside some other function it is still slow even on tuples.
Would it makes sense to add fast NTuple sort to Base?
