## Experimental

These features support building and applying operators, where an operator is a tensor whose
dimension names are split into a codomain (output) set and a domain (input) set. The API is
dimension names are split into an output set and an input set. The API is
still being refined and is subject to change. Build an operator with [`operator`](@ref) or
allocate one with [`similar_operator`](@ref), apply it to a tensor with [`apply`](@ref), and
recover its underlying tensor and name sets with [`state`](@ref), [`codomainnames`](@ref),
and [`domainnames`](@ref).
