Hi list,
I was playing around with namespaces and stumbled across this:
#!/home/steve/php5.3-200807070430/sapi/cli/php
<?php
namespace Foo;
use Foo::Bar as Something;
class Bar { }
?>
works fine, whereas
#!/home/steve/php5.3-200807070430/sapi/cli/php
<?php
namespace Foo;
{
use Foo::Bar as Something;
class Bar { }
}
?>
yields: Parse error: syntax error, unexpected T_USE
in /home/steve/namespaces/code/with_braces.php on line 6
Regards,
Stefan

"use" is a file-level construct, as far as I remember, so you can't
put it into block

I thought the only argument against using curly braces for namespaces
was exactly his example "you can use namespace foo; {} if you really
want to"?

OK:
namespace foo;
{
}
Not OK:
{
use Foo:Bar as Something;
}

Then that is a showstopper that effectively does not allow to use braces
around a namespace, so I'd boldly suggest either fixing the curly braces
notation to allow use statements or disallow curly braces around
namespaces, because as it is, it doesn't really seem useful.

I know, but namespace must be the first statement in a script, so I
can't put use before the namespace.

Trying to use curly braces around my namespace for readability. But I
can't put a use statement into these namespaces, neither can I put the
use before the namespace.
That means: I cannot use namespaces with curly braces combined with a
use statement. This makes the curly braces pretty pointless.

I think Stefan was just pointing out that allowing something that is
rarely useful is just needlessly confusing, because it makes you think
there is something you are missing.

It may be true in some cases, but in general PHP allows to do tons of
stuff that is not useful, or at least does not seem to be useful. But I
don't think it's productive to spend time on disallowing such things -
same time could be spent developing real features :)

I think it may be more productive to disallow it now, instead of
bogusifying bug reports and dealing with confused users later. My 2ct.

I don't think wasting effort on introducing artificial restrictions into
PHP just because somebody might erroneously submit a bug report is worth
doing.

is it possible to add custom (more user-friendly) error-message in this case?

I don't know. So far we never had custom user-friendly error messages in
parser. If you want to do it and know how, you can propose it, but
then I guess other parser errors should get same treatment.

well, looks like it is not an easy task for bison-parser.
it is worth to look at this problem after switching to lemon (5.4?)

The "use" can be used only as top-level statement.
Thanks. Dmitry.
