kurila18delta - what is new for Perl Kurila 1.8


This document describes differences between Perl Kurila 1.7 and Perl Kurila 1.8

Highlights In Perl Kurila 1.8

Core Enhancements

die and warn create error objects

Die 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.

Minor language changes

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.

Limited platform support

Perl Kurila has only been tested/build for x86_64-linux-gnu-thread-multi platform.
