Is it possible for a transducer to return more elements like:

[1, 2] -> [1, 1, 2, 2]

Is it possible for a transducer to sort a sequence like:

[2, 3, 4] -> [2, 3, 4]

What would those transducers look like in PHP?

This library is amazing btw

Lots of these are ideas from https://github.com/kevinbeaty/underscore-transducer

• partition_by
• compact
• tap

I'm getting a couple test failures with PHP 5.6.8:

FAILURES!
Tests: 53, Assertions: 89, Failures: 2.

The first failure seems to be caused by https://bugs.php.net/bug.php?id=68948 just like guzzle/guzzle#957 .

I did not dig into the second failure.

Did you ever solve the issue from guzzle/guzzle#957 besides disabling the test?
