PHP 5.4 code breaks PHP 5.3.1+ compatibility

[IvoWams]

spyc/Spyc.php

Line 188 in 4627c83

public static function YAMLLoadString($input, $options = []) {

This line and others has PHP 5.4+ style array brackets, however the version in composer.json still has requires >= 5.3.1.

I found a workaround when this library is a dependency of a third-party package. Set previous version as direct dependency and Composer will use that, e.g.:

{
 "config": {
    "platform": {
      "php": "5.3.3"
    }
  },
  "require": {
    "piwik/device-detector": "^3.11",
    "mustangostang/spyc": "0.6.2"
  }
}
