Paket: libperlx-maybe-perl (1.202-1)

[ Källkod: libperlx-maybe-perl  ]

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.

This package also includes Syntax::Feature::Maybe.
