Reimplementing virtual functions with
"const &" arguments wasn't behaving as
expected because these arguments were
copied.
Now, "const &" for arguments (in virtual
function reimplementation) is not implemented
as a copy.
In addition, now it's possible to declare
results as references always (also if const &).
See gsiTest.cc:1078 for example:
// gsi::arg_make_reference makes the function's return value
// always being taken as a reference
gsi::method<C_P, const CopyDetector &, const CopyDetector &, gsi::arg_make_reference> ("pass_cd_cref_as_ref", &C_P::pass_cd_cref)
