Summary	0000741: Unable to rich more value children level than 'max_depth' when obtain value from 'eval' command
Description	The issue appears if you use 'evaluate expression' feature in the IDE and need to open more children levels than configured in 'max_depth'. We use the minimum possible 'max_depth' value as it speed ups stepping (we reload stack frames data on every step using 'context_get' command). The only way - re-evaluate the whole expression. We need to have some kind of global cache of all evaluated values and clean it after each step.
Steps To Reproduce	Consider the following script: <?php function foo(){ return array(array(array(array(array(array(array(array(1)))))))); } echo 1; //breakpoint Eval 'foo()' expression when you will reach a breakpoint.
Additional Information	In PhpStorm we implemented a workaround for this problem and maintains our own evaluation cache in global variable $GLOBALS['IDE_EVAL_CACHE']. See attached xdebug log for more details. We assign an unique array key for every evaluated expression. When user ask for more children level we actually invoke property_get command for the expression substitutor.
