Bug description: wanted: eval() that works in a separate variable space
Description:
------------
I'd like a version of eval() that works in a separate environment
(variable namespace) so it can't clutter up the main script. Probably it's
best to give the name of an environment for example an object/array name as
a second argument to eval(), so the programmer can decide if two successive
calls of eval should work on the same or separate environments. There is
probably no problem with the main program having access to the namespaces
of the eval() calls.
For example (assuming that the separate environment is just an
object/array in the main program):
$a=1;
eval('$a=2;',$environment1);
echo $a; //shows 1
echo $environment1.a; //shows 2
eval('echo $a;',$environment1); //shows 2
eval('echo $a;',$environment2); //shows nothing or undefined
