NAME
kurila113delta - what is new for Perl Kurila 1.13
DESCRIPTION
This document describes differences between Perl Kurila 1.12 and Perl Kurila 1.13
Highlights In Perl Kurila 1.13
Values passed to subroutines or elements of an array or hash are no longer restricted to being a scalar, but can also be arrays or hashes. Making it possible to use complete data structures without needing references.
Core Enhancements
Values can be any type
A value can be a plain-value, array or hash. There are no distinctions between. The sigils are meaningless, and don't indicate anything containing the type
expand operator <
Arrays are no longer automaticly expanded to a list. The expand operator <
should be used to expand an array to a list.
Subroutines always return a scalar; wantarray
keyword removed
Subroutines always return a scalar, and behave as if called in scalar context. As a consequence the wantarray
keyword has been removed.
New operators nelems
and nkeys
nelems
returns the number of elements of an array. nkeys
returns the number of keys in a hash.
Only Hashes can be tied
Scalars, arrays and handles can no longer be tied.
Forward subroutine declarations are no longer supported.
KNOWN BUGS
Documentation
Documentation has not been updated for many of the changes for kurila.
Extensive use of lists
Lists are used in a lot of places where arrays are probably more appropriate.
Self referential assignment problems
Assigning some value to a part of itself behaves unexpected.
Tied hashes with complex data
Tied hashes do not work correctly with complex data structures. Assigning arrays or hashes to a value of tied hash might behave strange.
Limited platform support
Perl Kurila has only been tested/build for x86_64-linux-gnu-thread-multi platform.
