kurila113delta - what is new for Perl Kurila 1.13
This document describes differences between Perl Kurila 1.12 and 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.
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
Removes many unnecessary needs for references.
Arrays are no longer automaticly expanded to a list. The expand operator
< should be used to expand an array to a list.
Because types are no longer indicated by their sigil, they can't be automaticly expanded, so a special operator to expand a array is needed.
Subroutines always return a scalar, and behave as if called in scalar context. As a consequence the
wantarray keyword has been removed.
Because a subroutine can return an array, returning a list is not really needed and would only be confusing.
nelems returns the number of elements of an array.
nkeys returns the number of keys in a hash.
Because a array of hash in scalar context would just be the array of hash new operators are needed to return the number of elements in an array or hash.
Scalars, arrays and handles can no longer be tied.
Tied hashes are currently too much used to be easily be removed, so they are still allowed.
The don't really do anything.
Documentation has not been updated for many of the changes for kurila.
Lists are used in a lot of places where arrays are probably more appropriate.
Assigning some value to a part of itself behaves unexpected.
Tied hashes do not work correctly with complex data structures. Assigning arrays or hashes to a value of tied hash might behave strange.
Perl Kurila has only been tested/build for x86_64-linux-gnu-thread-multi platform.
