But why should the compiler care if I used a variable only once? Why does
it suspect it as a typo? I think I need to do something here to satisfy
the compiler. But I am not sure what it is!
BTW Mike, are you going to YAPC?

This probably isn't bogus. Do you only use this variable once?
Note that this is just a warning, not an error.
To "use a variable" means to have it on the RHS, usually. LHS only counts
as
defining it.
