Dmitry,
while looking at #55334 I discovered two issues regarding the handling
of properties and constants in threaded environments which might cause
race conditions.
The reproduce code for both issues is as simple as
?php new Exception; ?
and then hit it on a 8+ core box in threaded mode.
interesting, but this doesn't have anything in particular to do with
what I was talking about.
to the best of my understanding, an exception transfers control back
to the nearest calling code that has declared it is ready/willing/able
to resume control in the event that, somewhere up the
Rasmus,
What would that give you that a continuation passing paradigm
wouldn't? Why not tell the code what to call before you call it,
rather than bubbling up the stack (which then forces a fork of the
stack, as you need to partially unwind it, but keep track of what you
unwound for the resume).
Hi!
it's a wonderful mechanism with more uses than simply reporting errors
- the aspect of transferring control is what I find really interesting
about exceptions.
Exceptions should not be used for flow control. They are called
exceptions for a reason - to signify that something unusual

Hi!
While exceptions themselves may not be suitable for a general-purpose
control structure, they do embody one. It's an early-return mechanism that
you also see in some of the other control structures mentioned in this
thread (Python's generators, Common LISP's conditions). Even the return

Agreed. While restarting and resuming after exceptions could be useful,

IMHO, PHP is a great template language. This is what makes it so simple
and powerful, compared to other web languages.
So far, we have ?php, ?= and various legacy syntaxes like ?.
A suggestion : deprecate these old tags and replace them with a more
elegant and a shorter implementation.
