What is your opinion on the effectiveness of providing a facility to discover if a variable is defined (has/exists and table.has/table.exists) and also one to delete/undefine an existing variables and key/value pairs?
Even if no other behavior in Lua were changed, could that not provide what was sought after by the introduction of a new type?
