It would be very nice if the error was fixed, because it is  difficult to test alpha3 with a tons of Warnings: The use statement with non-compound name 'Nette' has no effect :-(

I have read it. 

Please, change status to Open.

"Note that for namespaced names (fully qualified namespace names containing namespace separator, such as Foo\Bar as opposed to global names that do not, such as FooBar), the leading backslash is unnecessary and not allowed, as import names must be fully qualified, and are not processed relative to the current namespace."

This explain it.

1) The warning says "The use statement with
non-compound name 'Foo' has no effect". This is not correct. I have posted example which show it HAS effect. Try it run in PHP.

2) "...the leading backslash is unnecessary and not allowed, as import names must be fully qualified, and are not
processed relative to the current namespace."

This is nonsense. If they are not processed relative, Foo is fully qualified - why developers MUST use leading backslash in some cases and MUST NOT is other cases - in all cases it is fully qualified. This should be fixed in documentation.

Please, change status to Open.
