Just now I can't think of an example for *generating* variable names only.
But there are very simple and important ones for *using* variable names:

local a1=1, a2=false
-- local a[1]=1, a[2]=false #<-- currently not allowed

For such default-constructs variable names and using "do" are really helpful.
