When using strict, you must make sure all of your variables are declared
within the proper scope. This means that all variables must either be made
lexical, by using my (restricts scope to current code block), fully
qualified using a package name (i.e. $package::varname), or declared as
local, which everyone here will be quick to let you know you shouldn't do
unless you have an excellent reason for doing so.
Good luck!
