You are, of course, perfectly right and my professional 
background would testify you to be correct.

But I didn't argue "performance is evil" - my point is 
"performance vs. realiability" and that it may quite well be a 
problem to favour performance too much.

performance is desirable, no doubt. But reliability is a conditio 
sine qua non in some environments.

To rephrase it: Thank you, Walter Bright, for giving us not only 
a performant language but one that also offers some very welcome 
mechanism to support reliability/safety.
