updated for version 7.3.146 Problem: It's possible to assign to a read-only member of a dict. It's possible to create a global variable "0". (ZyX) It's possible to add a v: variable with ":let v:.name = 1". Solution: Add check for dict item being read-only. Check the name of g: variables. Disallow adding v: variables.
