Disable composer drush extension when php < 5.3

Maybe something like this?

// ...
if (version_compare(phpversion(), '5.3', '>=')) {
  // Do Composer stuffs.
}

Probably should output a notice too.

Just ran into this on an old environment :-) .

I'm not sure this is fixed. Drush Composer crashes Drush when running PHP 5.2.9.

What error are you running into? Have you updated Drush Composer lately?

Here are the steps to reproduce (on a system running PHP 5.2.9):

drush dl composer-8.x-1.x-dev
drush status

Drush command terminated abnormally due to an unrecoverable error.                                           [error]
Error: syntax error, unexpected T_STRING in /.drush/composer/composer.drush.inc, line 89

Line 89 is $application = new Composer\Console\Application();

Something like this?

That works for me, I now see Composer requires at least PHP 5.3.2 in order to run properly. You are currently on PHP 5.2.9.. Thanks!

Thanks!
