Re: die/warn bug in elsif

die and warn are happening at runtime, and from the statement that begins on line 1, so it makes sense. The 0/0 is happening at compile time, where you're compiling line 4, so it also makes sense.

Well, "makes sense" because I know what's going on behind the scenes. :)

As a way of illustrating this point, here's the OP's first code block after being run through `perl -MO=Deparse buggy.pl`: `if (die '4') { (); }` [download] The B::Deparse module (called by the above command) shows you the Perl equivalent of what the interpreter sees at runtime.
