While many languages do offer "ease of use" and slow code, the ease of 
use suffers when one does run up against the speed problem with it. 
Then, you've got to figure out how to recode it in another language, or 
figure out how to interface other languages to the slow language for the 
speed critical parts. When you start doing that, the productivity 
advantages of the "ease of use" go out the window.
