[ANN] WACreditCard

Hello,

I reworked this from rubygems creditcard...


    WACreditCard types.  #(#mastercard #visa #americanExpress
#dinersClub #enroute #discover #jcb #bankcard #switch #solo)
       
    (WACreditCard number: '5276 4400 6542 1319') isCreditCard.
     
    (WACreditCard number: '5276 4400 6542 1319') is: #mastercard.

The latest addition to the Jetsam package,

Installer ss project:'311'; install: 'Kernel-Extensions'.
Installer ss project:'Jetsam'; install: 'Seaside28Jetsam'.

Or browse the package and just load the WACreditCard class

cheers

Keith

Isn't it a bit non idiomatic to have an instance of a class answer no to an
isClassType method?  Wouldn't isValid communicate the intent better than
isCreditCard?
