This weekend developers of PHP announced that name spacing will be possible (this is old news) but they will be using the backslash as separator (that’s the fresh news).
I really think that it’s quite weird to use the backslash instead of :: but they really thought it trough.
You can take a look at a table of pro’s and con’s they made here.
It ‘s cool to read the discussion of these guys here.
This is very strange. I know that personally I would like to see :: as the namespace operator. It just makes more sense.
