Truth!

Dear Log,

Interesting thing I saw in LWP/Protocol/http.pm yesterday:

    !!$conn_cache

It was used in initializing a flag for whether $conn_cache (which normally holds an object, or undef) was true.

!!!$true

That's not true, is it? Jesus.

be || !be

!! is a nice (and even somewhat cross-language) trick for "reduce-to-Boolean-truth-value". Fascistic type systems of course foil the trick,
requiring casts left and right ...

Jarkko, you are wise. But, this is Perl. Surely, there are no fascists about?

I said "cross-language". Follow the cross to other, less cavalier, languages that have a separate boolean type...
