The Perl 5 version of Chemistry::Elements was my first module, so
I'm making it my first Perl 6 module too. It's not complicated.
The module maps between element names (e.g. Rubidium), symbol (e.g. Ru ), and number (e.g. 37). It's multi-language aware although the language switching isn't sophisticated yet.
