Extract function name from Item_cache type object

Hi,

I am processing mysql query to extract function name from Item_cache
however Item_cache::print() method returns following string.

<cache>(now())

Is there any way to extract function name i.e. "now()" from Item_cache object?


Item_cache::setup(Item *item) method uses Item_func*  which is stored
as protected class member of Item_cache class (named example), I can
extract function name using Item_func::func_name() method however this
is protected member so I can not use this in client code.
