Actually the question is in the subject.
Is it possible to use VS 2012 instead of 2013?
I tried, but as I can see Rx depends on initializer_list and variadic templates.
Also from the build I can see that the following definition 'fires':
#if defined(_MSC_VER) && !RXCPP_USE_VARIADIC_TEMPLATES
// resolve args needs enough to store all the possible resolved args
#define _VARIADIC_MAX 10
Does it mean that there is a possibility to avoid variadic templates?
Just for additional context: we still use VS 2012, and I was curious if we could use Rx for one of the projects.
