| Subject: | "state" example in pod is broken |
Hi
This bug has been forwarded from http://bugs.debian.org/690735
There seem to be a small that the state example in POD is not working
this way. Following [1] it seems correct what is suggested by Anthony.
[1]: http://www.perlmonks.org/?node_id=794116
The original report follows:
Package: libparams-validate-perl
Version: 1.06-1
Severity: normal
File: /usr/lib/perl5/Params/Validate.pm
Show quoted text
>From the docs:
You can also use the "state" feature to do this:
use feature 'state';
sub foo {
state %spec = ( ... );
my %params = validate( @_, \%spec );
}
Doesn't quite work:
anthony@Zia:~$ perl -E 'state %foo = (a => 1)'
Initialization of state variables in list context currently forbidden at -e line 1, at EOF
Execution of -e aborted due to compilation errors.
The example should read something like this:
use feature 'state';
sub foo {
state $spec = { ... };
my %params = validate( @_, $spec );
}
Which, I confess, I haven't (yet) tested. Appears to be tradition :-P
