And much like those pencil sketches (many of which seem to end up in art 
museums if the painter is famous enough -- the Prada in Madrid was full of 
them), in many cases those prototypes become the product. And that's the 
problem with that sort of prototyping -- a language that focuses on ease of 
writing has to sacrifice ease of maintenance (simply because a lot less is 
written down), and if the product stays in that language there is going to 
be a big cost down the road.

I always do my prototyping in Ada for that very reason -- if the prototype 
works well enough (like the Web server and search engines did), it doesn't 
have to be rewritten just to add the robustness needed for something that 
will be used decades. But I doubt that I'd ever convince the masses of that 
value of that approach.
