Cool! It is a nice companion to my 8 byte "pretty much unique" generator [1], and could be integrated in my friendly URLs :).
However, I couldn't prove the case insensitivity of Base36, the #toNumber: ignores characters not present in the Characters array. I fixed Base36 toNumber: but broke Base62 tests :) self assert: (Base36 toNumber: (Base36 fromNumber: 16) asUppercase) will fail. Regards, -- Esteban.
