Thanks for the correction. I was not sure on that! :) My first idea was just
to type the (incorrect) option: template <typename T> virtual void foo(
T&... ), and doubting on whether that was correct I changed it into the
version above version avoiding to mention the template part. What about with
template compilation model with template instantiations for 'each from the
set you need'? Do compilers (which?) support template compilation? I tried
once with g++ but did not succeed.
