Probably you are in a running Julia session where you previously defined a version of `num_lang` that didn’t have the type restriction, and it’s still in memory, so the old version is being called instead of `num_lang(::Int)`. Restart Julia and it should work as expected.

PS. Quote your code (and don’t post screenshots): [Please read: make it easier to help you](https://discourse.julialang.org/t/please-read-make-it-easier-to-help-you/14757)
