=head1 NAME
Specio::DeclaredAt - A class to represent where a type or coercion was declared
=head1 VERSION
version 0.42
=head1 SYNOPSIS
my $declared = Specio::DeclaredAt->new_from_caller(1);
print $declared->description;
=head1 DESCRIPTION
This class provides a thin wrapper around some of the return values from
Perl's C<caller> built-in. It's used internally to identify where types and
coercions are being declared, which is useful when generating error messages.
=head1 API
This class provides the following methods.
=head2 Specio::DeclaredAt->new_from_caller($depth)
Given a call stack depth, this method returns a new C<Specio::DeclaredAt>
object.
=head2 $declared_at->package, $declared_at->filename, $declared_at->line
Returns the call stack information recorded when the object was created. These
values are always populated.
=head2 $declared_at->subroutine
Returns the subroutine from the call stack. This may be an C<udnef>
=head2 $declared_at->has_subroutine
Returns true if there is a subroutine name associated with this object.
=head2 $declared_at->description
Puts all the information together into a single string like "declared in
package Foo::Bar (.../Foo/Bar.pm) at line 42 in sub named blah".
