Hi,
I have written a call_user_method_array function that,
surprise surprise, calls a user method and passes arguments from an array - the object/class
equivalent of call_user_func_array.
The code is below. In the function table, I have made the second arg passed by reference, as it is
not very useful otherwise (a shortcoming of call_user_method).
I have CVS access and will add this code to basic_functions.c sometime tonight (in a couple of
hours), unless anyone objects!
