Actually at one point early on they did support a $this, but the way it was 
bound to an object was half-assed and incomplete so it was removed entirely 
from 5.3.  The intent was to then properly think through how that binding 
should happen and re-introduce it properly in 5.4.  I believe a consensus was 
reached on how that should happen but I'm not sure what its implementation 
status is at present.

I believe this is the relevant RFC:
