Hello,

I'm having some problem understanding the exact workings of the following code:

sub try (&@) {
    print "try();\n";
    my($try,$catch) = @_;
    eval { &$try };
    if ($@) {
        local $_ = $@;
        &$catch;
    }
}
sub catch (&) { print "catch();\n"; $_[0] }

try {
    die "foobar\n";
    print "OK";

} catch {
    print "FAILED!\n";
};
[download]

OUTPUT:

catch();
try();
FAILED!
did ok
[download]

-------------------

My question is why does the catch() sub gets called prior to the try() sub? My understanding was that two anonymous code references will be passed to try() and than catch() would be invoked from within try() therefore printing "try()" prior to "catch()".

Appreciate your help ;).
