Tim Peters <[email protected]>: > If this goes in (I'm not deadly opposed, just more opposed than in favor), > I'd like to see "else" used instead of the colon (cond "?" true "else" > false).

I have to say that I think any ternary syntax that mixes a single-character operator with a keyword would be intolerably ugly. > Now let's see whether people really want the functionality or are just > addicted to C syntax <ahem>. It's not that simple. People clearly want the functionality; we've seen ample evidence of that. Given that, I think the presumption has to be in favor of using the familiar C syntax rather than an invention that would necessarily be more obscure. > BTW, a number of other changes would be needed to the Lang Ref manual (e.g., > section 2.6 (Delimeters) explicitly says that "?" isn't used in Python > today, and that its appeareance outside a string literal or comment is "an > unconditional error"; etc). I'm certainly willing to fix that. -- <a href="http://www.tuxedo.org/~esr">Eric S. Raymond</a> [The disarming of citizens] has a double effect, it palsies the hand and brutalizes the mind: a habitual disuse of physical forces totally destroys the moral [force]; and men lose at once the power of protecting themselves, and of discerning the cause of their oppression. -- Joel Barlow, "Advice to the Privileged Orders", 1792-93
