flattening the name and syntaxcontext into the rename... HIDDEN INVARIANTS: 1) the first name in a Rename node can only be a programmer-supplied name. 2) Every Rename node with a given Name in the "to" slot must have the same name and context in the "from" slot. In essence, they're all pointers to a single "rename" event node.

IllegalCtxt

actually, IllegalCtxt may not be necessary.
