Hi,
As of r15039, :vtable and :vtable("...") are now both implemented. See
example code at the end of this email.
As of now, please use this new syntax. I have left in support for the
old "__"-prefix lookup as plenty of old code is using it; please note
that if you have a :vtable("xxx") and a "__xxx" then the first will be
called, not the second.
I'll leave it to Chip and/or Allison to decide how long the deprecation
cycle is for this.
Implementation wise, at the moment I'm just storing these entries in
"\0VTABLE\0" sub-namespace within the class namespace, however I'm not
sure I like this (feels like we got rid of one bit of namespace
pollution by adding another, albeit a less noticeable one). I don't see
another way to attach the VTABLE namespace to the main one, however. But
that's an implementation detail - even if we change that any
:vtable-using code will go on working fine.
Tests and some extra error checking code to come.

.sub main :main
$P0 = newclass [ "Test" ]
$P1 = new [ "Test" ]
$I1 = $P1[11]
print $I1
print "\n"
$S1 = $P1[11]
print $S1
print "\n"
.end
.namespace [ "Test" ]
.sub get_integer_keyed_int :method :vtable
.param int key
.return(42)
.end
.sub monkey :method :vtable("get_string_keyed_int")
.param int key
.return("monkey")
.end
