SubstParamsMap

dotty.tools.dotc.cc.CheckCaptures$.SubstParamsMap
final class SubstParamsMap(from: BindingType, to: List[Type])(using x$3: Context) extends ApproximatingTypeMap with IdempotentCaptRefMap

Similar normal substParams, but this is an approximating type map that maps parameters in contravariant capture sets to the empty set. TODO: check what happens with non-variant.
