Behat broken after installing extension

[danydev]

I'm using behat 3.2.1, as soon as I install the extension as the README says, behat does not work anymore. It doesn't give output regardless of the command run

    $ vendor/bin/behat -V
    behat version 3.2.1

After putting the extension on behat.yml Liuggio\Fastest\Behat2\ListFeaturesExtension\Extension: ~, any behat command terminate immediately with exit code 255 (and not output)

    $ #vendor/bin/behat -V
    #

The same for any other behat command (run tests, see scenarios, etc...)

I think this is because of Behat Version 3. In Behat2\ListFeaturesExtension\Extension.php the class implements an ExtensionInterface which does not exist anymore.

you should put Liuggio\Fastest\Behat\ListFeaturesExtension\Extension: ~ in behat.yml instead
