Re: Prototype "foo {...} bar {...}" is documented?

[diotalevi]

Any discussion on this should note that this syntax is noted in perlsub and that code relying on this has an increased likelyhood to leak memory. It isn't a particularly good perl idiom but mostly because of the various implementation considerations that are particularly noxious.

Yes, is documented with this example:

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

    try {
    die "phooey";
    } catch {
    /phooey/ and print "unphooey\n";
    };

Thanks I missed that.

... that code relying on this has an increased likelyhood to leak memory.

Any information on how the memory leakage occurs, and ways to avoid it, would be appreciated.

Re: Re2: Learning how to use the Error module by example discusses the memory leaks.

Thanks for taking the time to dig up that link.
