1. What dialect of C was it defined in? Is it still used in the
standard dialect (honestly, this is the first time I've ever seen it
before, but then again I am a younger generation user)?
Dialect? The ! operator is plain vanilla standard C. It takes a scalar
operand and returns 1, if it compares equal to 0, otherwise it returns
0. !!, i.e. two consecutive ! operators, is one of the oldest tricks in
the book, right next to (a > b) - (a < b) for comparison functions and
countless other idioms.
3. What's the real loss of going to `? :', beyond maybe 3 extra
keystrokes if it's easier for folks who may not be as experienced to
read?
I'd like my bikeshed grass green, please.
