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