NAME

kurila17delta - what is new for Perl Kurila 1.7

DESCRIPTION

This document describes differences between Perl Kurila 1.6 and Perl Kurila 1.7

Highlights In Perl Kurila 1.7

  • Block interpolation using {...} inside double quoted strings

  • Numeric comparison operators renamed.

  • Interpolation independent of the delimiter

  • No-escaping within single quotes

  • Substitute modifier s///e is removed

  • Obligatory m in front of matches.

  • Renamed readline operator <> to ~<

  • open must have a separate mode and filename

  • Removal of $]

Core Enhancements

Block interpolation using {...} inside double quoted strings

Inside double quoted strings {...} are interpolated in double quoted strings. They can also be used to evaluate code inside a replacement part of the substitute, for example s/<<=(.*)/{ eval $1 }/g >.

Numeric comparison operators renamed.

The numeric comparison operators < <= > >=, and <=> are renamed to +<, +<=, +>, +>= and <+> respectively.

Interpolation independent of the delimiter

Single quotes don't have any special meaning when used as delimiters for other constructors, i.e. m'$a' is the same as m/$a/.

No-escaping within single quotes

Single quotes do not do any escaping. This includes not escaping \\ and \'.

Substitute modifier s///e is removed

The subsitute modifieders s///e and s///ee to evaluate the replacement are no longer supported. The new interpolating {...} can be used instead.

Obligatory m in front of matches.

/PAT/ is longer supported and instead m/PAT/ must be used. Depending on the context a / will be interpreted as a divide operator or an error will be raised.

Renamed readline <> operator to ~<

The readline operator <FH> has been renamed to ~< *FH. There is no special syntax for ~<. There is no default *ARGV, and *ARGV must be explictly given to ~<

open must have a separate mode and filename

open should always be used with separate mode and filename. Using open with 2-arguments with a concatened mode and filename no longer works and gives an error.

Removal of $]

The version variable $] has been removed. $^V (eq "kurila-1.7") or $kurila::VERSION (eq "1.7") can be used instead
