I apologize for my probably naive question... Trying to decipher t/pmc/array.t, I began wondering what happens if you set a negative length to an array. It lead me to array.pmc::set_integer_native, which just forwards its size argument to list.c::list_set_length without any check.
list_set_length() seems to accept negative sizes. The implemented behaviour seems to decrease the size of the array by the absolute value of the arg, iff it is >= 0. For instance, if an array of size 5 is set to -10, it will have no effect. So my question is : - Is it expected (in List API, in PMC Array) ? - Where can I find the specification/documentation describing this kind of behaviour ? Thanks Karl
