It's a bad BC problem since it's harder to fix/notice.
In some cases, it seems works well while it's not.



The question is how often does this breakage actually happen in 
real

life and not theoretically on the mailing list.



Then we have different priority for BC problems :(
BC _with_ error is not as bad as BC _without_ error for me.



Theoretically I agree but if BC _without_ error happens very 
rarely then

I don't think it's that bad. In any case, we could always have an
E_MIGRATION for people migrating.



Great!
I personally prefer to have E_DEBUG, E_INFO and clean up error
level for functions. There about 2300 php_error/zend_error :)

I'll happily contribute for it.

E_INFO:

    Error like compatibility info (migration)

E_DEBUG:

    Error useful for debugging script but not appropriate
    for production scripts.

E_NOTICE

    Error that can be a bug in script but may be ingored.

E_WARNING

    Error taht cannot be ignored. (Error must be handled)

E_ERROR

    Fatal error.
Good idea. E_DEBUG may be a good alternative to php_printf(). Heh. Fine tuning errors is probably a good idea. E_PEDANTIC? A lot of errors that are E_NOTICE today would definitely be better off as E_PEDANTIC. Undefined array indexes come to mind. What else? E_INFO may be a bit vague (and probably attract a lot of "misc" errors). What about E_COMPAT for compatibility issues? E_PENDATIC, E_COMPAT, E_NOTICE, E_WARNING, E_ERROR Do you see E_PENDANTIC and E_NOTICE as much different? Can we differentiate between them?
