To be honest {} should only work for string offsets but we haven't
gotten around to changing this yet. I made the change in Zend necessary
to support this but never got around to fully implementing it.
I will try and address this in 4.0.3. DON'T use {} to index arrays. It
will not work in future versions. As for {} support within encapsulated
strings. It will work but as I said I just put in the infra-structure
but haven't implemented it yet. I thought no one had noticed :)
trust me, if there are some new things to play with, I`ll notice :)
I posted that report :) w the question if it´s intentional, I think
