Add getStream to interfaces.

[Metalaka]

Since #15 Hoa\Stream::getStream is public.

But because interfaces is commonly used in type hinting, this method can't be used safely.
eg: class Foo extends Hoa\Stream\IStream\In { … which doesn't implement getStream.

IMO this method should be present in all Hoa\Stream\IStream interfaces.

Hello :-),

I agree… So far, we assume every object of kind Hoa\Stream\IStream\* is also of kind Hoa\Stream. Does it make sense?

But this is a weak assumption. We can introduce a Hoa\Stream\IStream\Stream interface, that will be implemented by Hoa\Stream and maybe Hoa\Stream\IStream\* interfaces.

This will introduce a BC break. We should do that in the same time we bump the PHP version.

Thoughts?

Hoa\Stream\IStream\Stream must be implemented in Hoa\Stream\IStream\* to solve this issue.

Add an interface just for Hoa\Stream\Stream don't make sense.

Does it exist an issue for the next bump PHP version ?

Note: It's not a BC break because the library is still in beta. So it's fine.

Yup, you're right. That's what I was meaning.

So let's go :-).

And nop, no issue for the PHP5.4 drop.
