Description
For tuples there is
(1, 2) < (1, 3) #true
Would it make sense to have it for SVectors as well?
SVector(1, 2) < SVector(1, 3) # ERROR: MethodError: no method matching isless(::SVector{2,Int64}, ::SVector{2,Int64})
My use case is to sort a long Vector of small SVector elements.

Research direction
Start by locating the SVector implementation and any existing comparison methods, then compare its behavior with Julia tuple ordering and isless. Reproduce the SVector{2,Int64} example and add coverage for lexicographic ordering and sorting if the project’s existing tests provide a suitable entry point. Done means isless supports the shown SVector comparison without the MethodError.
