Too many languages ignore this.

@differentsmoke most people don't know this but named numbers probably* correspond to their casing. I wrote a helper that you might find useful.

uncti isUPPERCaseNumber (a) => (a == ONE || a == TWO || a == THREE ||  a == FOUR ||  a == FIVE ||  a == SIX ||  a == SEVEN ||  a == EIGHT ||  a == NINE ||  a == ZERO) 

* fact check me
