SimpleIdentityMap

dotty.tools.dotc.util.SimpleIdentityMap
See theSimpleIdentityMap companion object
abstract class SimpleIdentityMap[K <: AnyRef, +V <: AnyRef] extends K => V | Null

A simple linked map with eq as the key comparison, optimized for small maps. It has linear complexity for apply, updated, and remove.
