This document describes differences between Perl Kurila 1.5 and Perl Kurila 1.6

Highlights In Perl Kurila 1.6

Core Enhancements

An error is raised if an undefined subroutine is called.

If you call a undefined subroutine and it isn't defined you get an error. No attempt to use AUTOLOAD is made. The same applies of course to method calls: if the method isn't found an error is raised.


Prevents all the problems associated with AUTOLOAD

v-strings create 'version' objects.

Use of v-string create version objects, i.e. v1.2.3 would be similar to version-new("v1.2.3")>. Use of numbers with multiple decimal dots (like 1.2.3, thus without a 'v'), will give a compile error. There is no VSTRING type.


Promotes the use of version object for versions.

v-syntax must be used to do version checks

The VERSION in use Module VERSION LIST and use Module VERSION should be v-syntax, i.e. a 'v' followed by a digit, anything else will not be seen as a version.


Makes it more explicit that a version check is done.

Globs throw an error when stringified or numified.

There is a new function Symbol::glob_name($glob) which returns the name of the glob. Symbol::glob_name returns the name fully qualified, but without a leading '*'. For example: Symbol::glob_name($^STDERR) eq "main::STDERR"


Makes finding glob stringification errors easier.

Modules and Pragmas

Removal of the modules AutoLoader, AutoSplit, SelfLoader, Encode::Encoder, FileCache, Object::Accessor, NEXT, Shell

Most of these modules don't work without AUTOLOAD, but there should be no reason to use them.

Adjustment for removal of AUTOLOAD

Many modules have small adjust, because of the removal of AUTOLOAD. Including ExtUtils::Constant of which ExtUtils::Constants::WriteConstants should be used with PROXYSUBS = 1>.



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.
