And why not? IME, 50% to 98% of the code in a saleable app, even a numerical app, handles strings not num arrays, thanks for the need to interface with the user. (Nearer 98%, for an APL or J app, but that's down to the conciseness of math handling in APL or J.) To say that char and num arrays are treated the same way is not the whole story. This is not to detract from Devon's presentation, which I think is great.
