* Package name : libperlx-maybe-perl Version : 0.002 Upstream Author : Toby Inkster <toby...@cpan.org> * URL : http://search.cpan.org/dist/PerlX-Maybe/ * License : Artistic or GPL-1+ Programming Lang: Perl Description : return a pair only if they are both defined Moose classes (and some other classes) distinguish between an attribute being unset and the attribute being set to undef. Supplying a constructor arguments like this: . my $bob = Person->new( name => $name, age => $age, ); . Will result in the "name" and "age" attributes possibly being set to undef (if the corresponding $name and $age variables are not defined), which may violate the Person class' type constraints. . PerlX::Maybe checks that $x and $y are both defined. If they are, it returns them both as a list; otherwise it returns the empty list. -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
