UPDATE: Sorry, disregard this.
It did work, I made a mistake; I just shouldn't have been using maxdepth.
I do think it is good to know, however, that
find | grep '#' | xargs rm
will "clean up" funnily named files in a directory. Of course, some of those funnily named files are there... (0 Replies)

PerlX::Maybe(3pm) User Contributed Perl Documentation PerlX::Maybe(3pm)NAME
PerlX::Maybe - return a pair only if they are both defined
SYNOPSIS
You once wrote:
my $bob = Person->new(
defined $name ? (name => $name) : (),
defined $age ? (age => $age) : (),
);
Now you can write:
my $bob = Person->new(
maybe name => $name,
maybe age => $age,
);
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:
"maybe $x => $y, @rest"
This function checks that $x and $y are both defined. If they are, it returns them both as a list; otherwise it returns the empty list.
If @rest is provided, it is unconditionally appended to the end of whatever list is returned.
The combination of these behaviours allows the following very sugary syntax to "just work".
my $bob = Person->new(
name => $name,
address => $addr,
maybe phone => $tel,
maybe email => $email,
unique_id => $id,
);
This function is exported by default.
