Hi,
With this mail I don't want to talk to anyone directly, but I just want
to summarize the situation as far as I understand.
---
- Autoloading constants
---
No problem here: When the loading procedure fails, it gets converted to
a string like before. It may be a performance impact, but the code, that
relies on this "feature" gets flooded with warnings anyway.
---
- Autoloading functions
---
If I understood it right the only problem is, that *someFunction()* may
be in the global, as well as in the current namespace. This means, the
developer write a function in a namespace, that already exists in the
global scope, which remains to feel quite scary to me. Its way more
confusing, that (e.g.) *strpos()* don't behave, like expected and
learned for years now.
It will affect only single namespaces, because if you want to call a
function from another namespace you must prefix it with a qualified or
full-qualified namespace anyway.
And last but not least: Currently you must include the files containing
the functions yourself. This means, that existing code is _not_
affected, because as long as no one removes the include-statements, it
even not call any autoloading. But when the developers decides to remove
them, they probably wants to use the autoloading, what means, that they
(hopefully) understand, how it works.
However, in my opinion the important part is to just make a decision the
sooner, the better, as long as there are not too much creepy code out
there (I don't know any and I can't imagine, that there is). Because
functions with namespace are quite unhandy without autoloading and I
don't think, that there is much use of it.
So the 2 possible solutions:
1:
- test namespace
- test global
- load namespace
- load global
2:
- test namespace
- load namespace
- test global
- load global
Maybe
3:
- test namespace
- test global
- load global
- load namespace
would be a solution too, but it seems a little bit curious, when I use
namespaces, but it looks into the global scope first.
Regards,
Sebastian

Hi.
I would like to introduce this RFC which would provide function
autoloading through the spl_autoload facility without userland BC
breakage.
