Which time and time again has proven to be true...But why is that many
people are so relectant to accept this fact...

I hope it isn't off topic but you get people who say "hey I can do that
same code in less number of keystrokes" and in the end the generated
assembly is still the same.

Another thing is that many people "falsely" belive is that using the ?
operator provides faster code than a simple if statement. which is quite
wrong. The ? operator causes reduced readability with no extra gain...a
neagtive result in anyones equation...
