- Subject: Exposure of nil to end-users

I am using Lua as a language that allows end-users to manipulate
My problem is that I'm not sure how to expose NULL values to the user.
In this example, value = nil
User Types: value .. "abc"
User Expects: 'abc'
User Gets: Error: attempt to concatenate a nil value
Has anybody had a similar problem, and how have you dealt with it?
