Hey dear #AlchemistFriends! I’m creating a 
validation engine , in order to put several day-to-day validation rules all together!!!
If you folks could take a look real quick and provide me some feedback, that would be just fantastic to listen from you 
https://github.com/elixir-validation/validation
Some validation rules for instance: Email, Credit Card, Barcode, IBAN, WordCount, PostalCode (us, uk, br…), CountryCode, MacAddress.. and +65 other ;- )
P.S.: I’m very-very-very new to the Elixir ecosystem. Literally just 2 weeks learning the language & writing code. Please 
be a bit merciful (hehe). Thanks for your understanding.

Just to point out, while it is deprecated it is perfectly valid email:
And I believe your regex will mark it as invalid. You have 2 options how to approach such data as this one:
Otherwise it ends somewhere in between and can be a little bit confusing (ignoring fact that such long regex is very easy to abuse and force engine to do matching in
O(n^2)).EDIT:
Also it is hard to tell in your
alphanumeric/alpha/etc. work within Unicode groups or not. Is string٠numeric or not? This character is U+0660 Arabic-Indic Digit Zero, so it is digit, but I think that You do not expected that.
