Why would it be a problem to define and use a function just about
anywhere? Isn't that what having function be a first class object is all
about? As for specific uses, there are many. For example smalltalk often
uses something similar (a block, which is technically a full context in
many versions of the language) as an iteration function over an array or
other collection.

If pushed I'm sure I can come up with specific examples in Lua, though
I've only played around with the language a little bit, and will be glad
to do so if anyone feels it's necessary.
