Exactly. Due to asymmetry of methods and vtables, the latter are not accessible as methods. You have to use the equivalent opcode: $I0 = elements ar_pmc But you can code a PIR wrapper for it: .namespace ['FixedBooleanArray'] .sub 'elements' :method $I0 = elements self .return ($I0) .end usable as: $I0 = ar_pmc.'elements'() > In fact, what I really want to do, for debugging purposes, is to add a > custom method in the FixedBooleanArray.pmc (e.g get_allocated_size() ) and > be able to call it > from PIR test code. As you need PMC internals for this, you'd have to add it to the .pmc itself (temporarely): METHOD INTVAL get_allocated_size() { return PMC_int_val2(SELF); /* or whatever */ } > Thanks > Karl Forner HTH, leo
