Is it (yet?) possible to use tailcalls from/to object methods?
I looked through the various pod files and couldn't find anything,
and I remember seeing some discussion about tailcalls in general
a couple of months ago but didn't stumble across the answers in the
archives.
I'd appreciate any gentle
1) we now have a rather complete set of opcodes that return a new result
PMC, all prefixed by "n_", e.g.
n_add Px, Py, 1
n_abs Px, Py
These opcodes can/should be used by HLLs like Python, which have the
semantics of immutable scalars and newly created result PMCs.
2) Tests for all these opc

Well, there is a C opcode in ops/object.ops. But I don't
know, if it works correctly.
$ find t -name '*.t' | xargs grep tailcall
t/pmc/sub.t:tailcall P0
t/pmc/sub.t:tailcall P0
Isn't there something like:
{
my $s does LEAVE { destroy $s } = new CoolClass;
# ... do stuff that may throw ...
}
Or something like that?

Not currently. There used to be a C opcode, but I've deleted
it
pmc2c.pl says:
=item C
Calls the overridden implementation of the current method in the nearest
superclass, using the static type of C.
=item C
As above, but uses the actual dynamic type of C.
but for a dynamic class, if I try to use it I get errors such as:

Refcounting does this with a little overhead, but in a fast and
deterministic O(1) way.
This is the first half of an apples-to-oranges comparison, and so is

Another note: we might as well create a C vtable call as well. We
need some such (and an opcode) anyway for HLL objects.
How could/should that beast look like?

>>> help(super)
class super(object)
