Greg: You say that the old java-package-style definition still works, in
addition to braces. I presume then that the following are equivalent:
<?php
namespace foo;
class Bar {
...
}
?>
<?php
namespace foo {
class Bar {
...
}
}
?>
What happens if you mix them?
<?php
namespace baz;
namespace foo {
class Bar {
...
}
}
?>
Is the full name of the class then foo::Bar, baz::Bar, or foo::baz::Bar?
Would the compiler have a heart attack if someone did:
<?php
namespace foo {
namespace baz {
class Bar { ... }
}
}
?>
instead of:
<?php
namespace foo::baz;
class Bar { ... }
?>
or:
namepsace foo::baz {
class Bar { ... }
}
I don't know anywhere near enough about the engine code to be able to read
your patch below, so I'm just trying to understand all the various
implications of this syntax.

"If nature has made any one thing less susceptible than all others of
exclusive property, it is the action of the thinking power called an idea,
which an individual may exclusively possess as long as he keeps it to
himself; but the moment it is divulged, it forces itself into the possession
of every one, and the receiver cannot dispossess himself of it." -- Thomas
