|| die or or die :)

I'm just surprised that I've never seen a problem using it exactly as I've written it above, which I do with great regularity. The docs say that the calling signatures are

open FILEHANDLE, EXPR
[download]

and

open FILEHANDLE
[download]

My syntax falls into the first case, but what constitutes an "EXPR"? I've got a string, the || operator, then the die -- does that qualify as an EXPR? I'll have to poke around the docs some more.....

Oh. Playing around with the right and wrong way shows me that my "|| die" syntax fails without die-ing.

Yes, it does (as you seem to have discovered): since `\|\|` is higher precedence than the comma, it's parsed roughly as `open ( FILEHANDLE, ("filename" \|\| die( ...) ) );` Since your string is always true, the die is never reached.

||

higher precedence

open ( FILEHANDLE, ("filename" || die( ...) ) );

die

If God had meant us to fly, he would *never* have given us the railroads.
