3.4/develop

Fully embraced the composer way of doing things, added requirement of PHP 5.4+, and added some fancy new 5.4 stuff.
I agree also with your point and we could absolutely maintain code with arrays like previous 5.4 easily. And use only 5.4 new stuff if only absolutely needed. I think its quite complex to make everyone happy :(

For instance I want to use 5.5 or newer whenever available but I make money by distribution of our code and make it available as many people as possible therefore having more compatibility means for me I can reach more people. As said really complex to make everyone happy :(
