Actually we can (I think). There are to possibilities:

new namespace::class()
new namaespace::namedspace::class()

and so on, or:

namespace::class::functoin()
namespace::function()

and so on. That is, when detecting braces after it and a new in front
than it is a class. If there is no new in front it must be a function and
autoload needs to be called for all but the last part. With new it needs
to be called for all parts. Since the compiler already knows whether it
generates a ctor call we must have an issue that should be fixable.


Best regards,
 Marcus
