kurila119delta - what is new for Perl Kurila 1.19
This document describes differences between Perl Kurila 1.18 and Perl Kurila 1.19
Subroutines can be used as l-values.
Subs declared using a formal paramter defintion like
sub foo( = $x ) { ... } foo() = "value";
If the assignment is optional the sub can be used in combination with a operator with modifies its argument. For example:
sub foo( ?= $x ) { ... } foo() += 3;
This will first call foo twice, once without $x and with $^is_assignment set to false, then again with the computed value for $x and with $^is_assignment set to true.
foo
$x
$^is_assignment
Intuitive syntax for setting values using subroutines.
Subroutines can have formal parameters like sub foo($x, $y) or sub foo($x, @< $y). Actual parameters are mapped to formal parameters similar pattern matching. The number of actual parameters is checked at compile to match the number parameters expected.
sub foo($x, $y)
sub foo($x, @< $y)
Expressive formal parameters. Allows compile-time argument checking.
local
undef
Using local does automaticly reset the operand to undef.
Allows local to be used on values which should not be reset to undef.
STDOUT
STDERR
STDIN
$^STDOUT
$^STDERR
$^STDIN
The standard file handle STDOUT, STDERR, STDIN are renamed to $^STDOUT, $^STDERR and $^STDIN
Reduce the use of globs.
