There's more than one possible meaning of "closure" in the context of
programming languages?  A closure is an encapsulation of a bit of executable
code along with all the variables in the scope of that code. It can be run
later, from a different scope, and still have access to the encapsulated
variables even if they would otherwise no longer exist.
