Execution of -e aborted due to compilation errors (#1)
    (F) You've said "use strict" or "use strict vars", which indicates
    that all variables must either be lexically scoped (using "my" or 
+"state"),
    declared beforehand using "our", or explicitly qualified to say
    which package the global variable is in (using "::").

Uncaught exception from user code:
        Global symbol "@ARG" requires explicit package name at -e line
+ 1.
Execution of -e aborted due to compilation errors.
