Re^2: initialise state variable from list context, NOT!

in thread initialise state variable from list context, NOT!

Thanks for the quick answer. The reason I thought I may get it to work with some hints for the compiler is that this is allowed

state %record;

%record = (
    getting => 'url',
    url     => 'http://',
    match   => '',
    getting => '',
    alarm   => 'no',
);

Is an empty hash considered as a safe case? Where is the border of what I can get away with?

Cheers,

One of border cases is:

sub foo {
    (my $foo, state $bar) = (f(), g());
    ...
}

foo;
foo;  # Should g() be called?

As for state %record;, that is allowed. It's state in a list assignment that is disallowed. But note that

state %record;
%record = ( ... );

doesn't give you any benefits over

my %record = ( ... );

You will have to write it as

state %record;
%record = ( ... ) unless keys %record;
