I suggest one also meditate on this: &&= and ||= exist; and= and or= do not.

S'funny, but that is exactly what makes them (and & or) so useful in boolean conditions.

But you will not see that usefulness until you cease making an wholly artificial distinction beween "flow control" and whatever you consider to be "non-flow control".

This: my $x = isSomething() and isSomethingElse() ? $p : $q;

is just as much "flow control" as doSomthing() or doSomethingElse();

as is: if( isSomething() and isSomethingElse() ) { ... } else { ... };

    You highlighted "wholly artificial" as if it matters, as if a programming concept could be anything else? It's a funny argument to make.

      It's not the "programming concept" that matters. (Whatever that ethereal phrase may mean to you?)

      It is the wholly artificial distinction between "flow control" and whatever is the complement of that in this context?

        I make a whole lot of "wholly artificial distinctions". Most people call them "programming styles". Programing styles can be every shade of good and bad, but just pointing out it's a programming style isn't an argument.
