rationale:
To improve the productivity of Perl, we try to implement around 200
methods inspired by Ruby collections for Perl array and hash.
We build up those methods based on the Perl tie 'StdArray' and tie
'StdHash' features. We call these implementations Ruby::Array and
Ruby::Hash. We try to make these implementations can be treated as
the ordinary Perl array and hash. All modules which are design for
Perl array and hash can be used on Ruby::Array and Ruby::Hash as
well.
Furthermore, we made many improvements on the behaviors of
Ruby::Array and Ruby::Hash. 1. We provide friendly api to build up
Ruby::Array and Ruby::Hash quickly. For example: ra( 1, 2, 3 ) -> [
1, 2, 3 ] ra( [ 1, 2, 3 ] ) -> [ 1, 2, 3 ] ra( ra( 1, 2, 3 ) ) -> [
[ 1, 2, 3 ] ] rh( { 'a' => 1 } ) -> { 'a' => 1 } rh( 'a' => 1 ) -> {
'a' => 1 } rh( 'a', 1 ) -> { 'a' => 1 }
2. Ruby::Hash enumerates its values in the order that the
corresponding keys were inserted. In other words, it becomes an
ordered hash.
3. When using array or hash to be the key of a Ruby::Hash, it
automatically translates the data structure into string form. For
example: rh( [ 1 , 2 ] => 3 ) -> { [ 1, 2 ] => 3 } instead of {
ARRAY(0x7fa4320052b8) => 3 }
4. Complex data structure comparison becomes mush easier. For
example: ra( 1, { 2 => 3 } ) == [ 1, { 2 => 3 } ] # return 1
5. Many operators are overloaded to make Ruby::Array and Ruby::Hash
easier to use. For example: ra( 1, 2 ) << 3 -> [ 1, 2, 3 ] ra( 1, 2,
3 ) - [ 3, 4 ] -> [ 1, 2 ] ...
6. Fluent interface make code much easier to read and use. For
example: rh( 1 => 2, 3 => 4 )->to_a->flatten->map( sub { $_[0] * 2 }
) -> [ 2, 4, 6, 8 ]
