An implementation of ITags designed for AstNode.
It is supposed to be possible to clone AstNode quickly; to support extra tags, we need to be able to clone the tags quickly too, so it makes sense to store them in a WList. To make cloning as quick as possible, we derive from WListProtected. To optimize access to tags, we use the UserByte of WListProtected to hold the index of the last tag that was used. This ensures tags can be accessed quickly by code that only uses a single tag.
