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'()

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 */
}
