Re: routine_id() is not working

The 3.1 standard library is in the include directory and the 4.0 library is in include/std. In general, you should use the stuff in include/std for new development. The older stuff is for backwards compatibility with legacy code.
That is not documented on http://openeuphoria.org/docs/std_os.html#_1860_sleep .
I'm not sure what we'd put there. Still, I didn't immediately find anything talking about the 3.1 to 4.0 transition, which I thought we had. Possibly in the wiki, although the "What's new in 4.0" at the beginning of the manual says, "Euphoria has a brand new standard library consisting of over 800 public members."
I have a further question, since i hadn't considered mixing includes for 3.1 and 4.0 which have the same function names. Lets say i do:
include "C:\\Euphoria-10-Feb-2013\\include\\std\\os.e" include "C:\\Euphoria-10-Feb-2013\\include\\misc.e"
(and we can say i did it, because i did it), then i do:
id_num = routine_id("os:sleep") id_num = routine_id("sleep") id_num = routine_id("misc:sleep")
both id_num for sleep and misc:sleep are -1. Of course, this does work:
include "C:\\Euphoria-10-Feb-2013\\include\\misc.e" as misc id_num = routine_id("misc:sleep")
So using namespaces to identify the sleep in misc.e works, but since the sleep in os.e is already namespaced away from misc.e, shouldn't this work too:
include "C:\\Euphoria-10-Feb-2013\\include\\std\\os.e" include "C:\\Euphoria-10-Feb-2013\\include\\misc.e" id_num = routine_id("sleep")
This also works:
include "C:\\Euphoria-10-Feb-2013\\include\\std\\os.e" as os id_num = routine_id("os:sleep")
even tho os.e is already namespaced internally to itself. So maybe if we get into the habit of always using "as" in includes, or better yet: the interpreter does this automagically, it might make life a lil easier. I think the error msg could get more informative also:
include "C:\\Euphoria-10-Feb-2013\\include\\std\\os.e" as os include "C:\\Euphoria-10-Feb-2013\\include\\misc.e" as misc id_num = routine_id("sleep") puts(1,"\n") id_num = routine_id("sleep") -- Error line 3 : pick sleep from os or misc -- Error line 5 : pick sleep from os or misc
Because right now,
include "C:\\Euphoria-10-Feb-2013\\include\\std\\os.e" as os include "C:\\Euphoria-10-Feb-2013\\include\\misc.e"
does not error, but the sleep in misc.e is unavailable. Or is that an undocumented feature?
And the reason i appended my question to this as i did is so you can add your answer to the section on namespaces and resolving the mix in the routine_id() section.
