clearer
clearer;
clearer '_clear_attr';
# equivalent to
has attr => ..., clearer => '_clean_attr';
The clearer function returns a list suitable for configuring the clearer portion of the attribute declaration.
coerce
coerce;
# equivalent to
has attr => ..., coerce => 1;
The coerce function return a list suitable for configuring the coerce portion of the attribute declaration.
def
def attr => sub { 1 };
# equivalent to
has '+attr' => (..., default => sub { 1 });

is;
The is function returns a list from a list, and acts merely as a pass-through, for the purpose of being a visual/descriptive aid.
isa
isa sub { ... };
# equivalent to
has attr => ..., isa => sub { ... };
The isa function returns a list suitable for configuring the isa portion of the attribute declaration.
lazy
lazy;
# equivalent to
has attr => ..., lazy => 1;
The lazy function returns a list suitable for configuring the lazy portion of the attribute declaration.
optional
optional;
# equivalent to
has attr => ..., required => 0;
The optional function returns a list suitable for configuring the required portion of the attribute declaration.
predicate
predicate;
predicate '_has_attr';
# equivalent to
has attr => ..., predicate => '_has_attr';
The predicate function returns a list suitable for configuring the predicate portion of the attribute declaration.
reader
reader;
reader '_get_attr';
# equivalent to
has attr => ..., reader => '_get_attr';
The reader function returns a list suitable for configuring the reader portion of the attribute declaration.
required
required;
# equivalent to
has attr => ..., required => 1;
The required function returns a list suitable for configuring the required portion of the attribute declaration.
ro
ro;
# equivalent to
has attr => ..., is => 'ro';
The ro function returns a list suitable for configuring the is portion of the attribute declaration.
rw
rw;
# equivalent to
has attr => ..., is => 'rw';
The rw function returns a list suitable for configuring the rw portion of the attribute declaration.
trigger
trigger;
trigger '_trigger_attr';
# equivalent to
has attr => ..., trigger => '_trigger_attr';
The trigger function returns a list suitable for configuring the trigger portion of the attribute declaration.
weak_ref
weak_ref;
# equivalent to
has attr => ..., weak_ref => 1;
The weak_ref function returns a list suitable for configuring the weak_ref portion of the attribute declaration.
writer
writer;
writer '_set_attr';
