Actually both problems are not GOI related, it's just Perl:

Do not *invoke a method* when you actually want to *call a function.*
module_name->function_name() is the same as
module_name::function_name('module_name'):

Your extraneous quotes say that you're *not* calling set_language with $lang,
but with *another* value representing $lang's *stringification*.

+ one more issue:
*our $VERSION = "0.01";*

Please do not use *interpolating* quotes needlessly:

Good luck!
