Re[8]: mixing of asign() and assign_by_ref() overwrites external vars

OK, let's close the theme.

Maybe  it is useful now to write to the Smarty documentation that
behavour  of  assign() and assign_by_ref() is EXACTLY the same as
behavour of = and =& operators in PHP?

B> Dmitry, I'm curious -- why are you pushing this so heavily?
Because  I have to pass English exams in the end of June and need
some practice. (-;

No-no, it's joke, of course.

I  just  trying  to understand Smarty developers point of view to
any  changes  -  before  offering  my  own  big  release (if your
remember,  I'm  trying  to  "push", as you have said, line number
synchronization  ideology). How else could I do it if I would not
speak and discuss impugnable things? (-;

And, of course, I am still agreed with Sebastian Mendel.

Forget about that. (-;

Not quite.

Operators  "="  and  "=&"  works  in PHP5 IDENTICAL to PHP4. But,
"objects"   are   not   objects  now,  only  lightweight  "object
pointers". It is pointer copied by "=", not object itself, that's
why it is safe now to use "=" in PHP5.
