=head1 SYNOPSIS |
248
|
|
|
|
|
|
249
|
|
|
|
|

|
=head1 DESCRIPTION |
252
|
|
|
|
|
|
253
|
|
|
|
|
These are light-weight junction objects covering most of the functionality |
254
|
|
|
|
|
provided by L<Syntax::Keyword::Junction>. They provide the objects created by |
255
|
|
|
|
|
the C<all_items> and C<any_items> methods defined by |
256
|
|
|
|
|
L<List::Objects::WithUtils::Role::Array::WithJunctions>. |
257
|
|
|
|
|
|
258
|
|
|
|
|
Only the junction types used by L<List::Objects::WithUtils> ('any' and 'all') |
259
|
|
|
|
|
are implemented; nothing is exported. The C<~~> smart-match operator is not |
260
|
|
|
|
|
supported. See L<Syntax::Keyword::Junction> if you were looking for a |
261
|
|
|
|
|
stand-alone implementation with more features. |
262
|
|
|
|
|
|
263
|
|
|
|
|
The junction objects produced are subclasses of |
264
|
|
|
|
|
L<List::Objects::WithUtils::Array>. |
265
|
|
|
|
|
|
266
|
|
|
|
|
See L<List::Objects::WithUtils::Role::Array::WithJunctions> for usage details. |

=head2 Motivation |
269
|
|
|
|
|
|
270
|
|
|
|
|
My original goal was to get L<Sub::Exporter> out of the |
271
|
|
|
|
|
L<List::Objects::WithUtils> dependency tree; that one came along with |
272
|
|
|
|
|
L<Syntax::Keyword::Junction>. |
273
|
|
|
|
|
|
274
|
|
|
|
|
L<Perl6::Junction> would have done that for me. Unfortunately, that comes with |
275
|
|
|
|
|
some unresolved RT bugs right now that are reasonably annoying (especially |
276
|
|
|
|
|
warnings under perl-5.18.x). |

|
|
This code is originally derived from L<Perl6::Junction> by way of |
281
|
|
|
|
|
L<Syntax::Keyword::Junction>; the original author is Carl Franks, based on the |
282
|
|
|
|
|
Perl6 design documentation. |
