in thread Does eval cause that much of a performance hit?

I agree with you, except that we've now moved so far from the OPs point: prefer things like a three line if construct than a trailing if., and perrin's response that we're almost on a different subject. 'sides which, the same people that eshew the trailing if also tend to reject the ternary as too complex/confusing/unclear/short.

as an explicit undef is pretty dumb,

I'm not sure where you saw the explicit undef?

    I don't think the topic has drifted.

    The point I wanted to make was that a ternary conditional is a viable alternative to introducing a scope (a 3-line if), if statement modifiers are not favoured by local shop practices. (Which is a reasonable edict, even if I don't agree with it myself).

    I'm not sure where you saw the explicit undef?

    There was none. It came about in my snippet from employing a ternary, which requires one to put something "in the else" part.
