 Posted: Sun Apr 25, 2004 1:43 am Post subject: Other binary and unary shorthand assignment operators |
 |
|
Why aren't there shorthand &&= and ||= operators? Is it related to the
short circuit evaluation and sequence points?
Why aren't there unary shorthand operators ~=, !=, -=, and += ? For
example:
x = ~x;
could have become
~= x;
As with binary shorthand operators, this would have been more concise,
less error-prone, and potentially more efficient. ( Imagine if x was a
matrix and ~ signified inversion. Even without ~=, one could have used
compositors, but that is not the point here.)

-= and += are already in use for the binary operators.

What's the problem?
z = y - - x; // - is overloaded
y -= -= x; // -= is now overloaded

Even the result of all the built-in assignment operators, including
the shorthand ones, are lvalues. So what's the problem with ~= etc?
