=head1 NAME
Parse::Method::Signatures::Param - a parsed parameter from a signature
=head1 ATTRIBUTES
All attributes of this class are read-only.
=head2 required
Is this parameter required (true) or optional (false)?
=head2 sigil
The effective sigil ('$', '@' or '%') of this parameter.
=head2 type_constraints
=over
B<Type:> L<Parse::Method::Signatures::TypeConstraint>
B<Predicate:> has_type_constraints
=back
Representation of the type constraint for this parameter. Most commonly you
will just call L</meta_type_constraint> and not access this attribute directly.
=head2 default_value
=over
B<Type:> Str
B<Predicate:> has_default_value
=back
A string that should be eval'd or injected to get the default value for this
parameter. For example:
$name = 'bar'
Would give a default_value of "'bar'".
=head2 constraints
=over
B<Type:> ArrayRef[Str]
B<Predicate:> has_constraints
=back
C<where> constraints for this type. Each member of the array a the string
(including enclosing braces) of the where constraint block.
=head2 param_traits
=over
B<Type:> ArrayRef[ Tupple[Str,Str] ]
B<Predicate:> has_traits
=back
Traits that this parameter is declared to have. For instance
$foo does coerce
would have a trait of
['does', 'coerce']
=head1 METHODS
=head2 to_string
=head2 meta_type_constraint
Get the L<Moose::Meta::TypeConstraint> for this parameter. Check first that the
type has a type constraint:
$tc = $param->meta_type_constraint if $param->has_type_constraints;
=head1 SEE ALSO
