Here's a different approach that will accomplish the same
thing via can(). The upshot of this is that we don't need
to change the APR::Error::strerror() signature; all
current tests pass with this patch.
Comments?
+1, but you probably need to deal with the case where can() fails?
+ my $strerror = $_[0]->can("strerror");
Carp::confess("$_[0]->{func}: ($_[0]->{rc}) " .
- APR::Error::strerror($_[0]->{rc}));
+ $strerror->($_[0]->{rc}));
