Summary : Return a pair only if they are both defined
Description :
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.
(Note: if you are the _author_ of the class in question, you can solve this
using MooseX::UndefTolerant. However, some of us are stuck using
non-UndefTolerant classes written by third parties.)
To ensure that the Person constructor does not try to set a name or age at
all when they are undefined, ugly looking code like this is often used:
my $bob = Person->new(
defined $name ? (name => $name) : (),
defined $age ? (age => $age) : (),
);
or:
my $bob = Person->new(
(name => $name) x!!(defined $name),
(age => $age) x!!(defined $age),
);
A slightly more elegant solution is the 'maybe' function.
