kurila18delta - what is new for Perl Kurila 1.8
This document describes differences between Perl Kurila 1.7 and Perl Kurila 1.8
die and warn create error objects
$SIG{__DIE__} and $SIG{__WARN__} renamed to ${^DIE_HOOK} and ${^WARN_HOOK}
Implicit local ${^DIE_HOOK} = undef around an eval
Minor language changes
die and warn create error objectsDie and warn now create error objects. These include a full stack dump.
Use $@->message to get the error message.
Having a complete stack trace makes debugging easier.
$SIG{__DIE__} and $SIG{__WARN__} renamed to ${^DIE_HOOK} and ${^WARN_HOOK}The die and warn handlers have been renamed to ${^DIE_HOOK} and ${^WARN_HOOK}.
When called these functions hould receive as first argument an error object.
${^DIE_HOOK} and ${^WARN_HOOK} are no signal handlers.
=head2 Implicit C<local ${^DIE_HOOK} = undef> around an C<eval>
Implicit local ${^DIE_HOOK} = undef around an eval
Makes ${^DIE_HOOK} suitable for error reporting without interfering
with eval.
The operators lt, le, gt, ge have been removed.
lvalue subroutines are no longer allowed.
Single quotes (') are no longer allowed in names.
Depth-first method resolution is no longer supported.
Documentation has not been updated for many of the changes for kurila.
Perl Kurila has only been tested/build for x86_64-linux-gnu-thread-multi platform.
The INSTALL file for how to build Perl Kurila.
The README file for general stuff.
