[svk-devel] YAML::Syck and B::Deparse

[Michael Hendricks]

Since version 0.46_01, YAML::Syck can serialize code references.  To do
so, it loads B::Deparse.  However, it loads B::Deparse even if there are
no coderefs to serialize.  B::Deparse is a large module and SVK pays a
small penalty for compiling it (.2s on my slow hardware) for every
command.

If anyone here knows how to modify the YAML::Syck XS so that it loads
B::Deparse only when needed, that would be the best solution.  Without
a solution from upstream, inserting the following into bin/svk
accomplishes the same goal.


BEGIN {
    unshift @INC, sub {
        my ($code, $file) = @_;
        return if $file ne 'B/Deparse.pm';
        my $foo = '0';
        open my $fh, '<', \$foo or die $!;
        return $fh;
    };
}

Is blacklisting B::Deparse too evil for production?
