Subject: [PATCH] new function Scalar::Defer::is_deferred
Date: Fri, 28 Dec 2007 12:09:00 -0200
To: "Audrey Tang" <audreyt [...] audreyt.org>, bugs-Scalar-Defer [...] rt.cpan.org
From: "Adriano Ferreira" <a.r.ferreira [...] gmail.com>
Hi, Audrey. I am sending a patch to Scalar-Defer-0.12 for your consideration. The proposed changes are summarized below. Kind regards, Adriano Ferreira ### new exportable function 'is_deferred' Why? If you want to use the deferred value as a generator (in the same place you could use a regular value), you may detect this with 'is_deferred' and then force it. my $regular_value = is_deferred($value) ? force($value) : $value; (I used that at the recent Class::Constructor::Factory 0.001, but had to include a hack which knows "too much" about Scalar::Defer guts) ### 'private' in use Class::InsideOut qw( private register id ) was unused. Removed in the patch. (Not sure if it has hidden implications.) ### FALSE_PACKAGE and DEFER_PACKAGE were both '0' Apparently FALSE_PACKAGE should have been superseded by DEFER_PACKAGE (and it is, with an only exception of the line @{FALSE_PACKAGE().'::ISA'} = ('Scalar::Defer::Deferred'); ). And this is a little misleading because all the rest of the code used DEFER_PACKAGE. So FALSE_PACKAGE was removed too. ###
