SFINAE causes a *silent* failure during an *attempt* to instantiate a template. The only template here is tuple_for_each_helper which was already instantiated, before the actual failure could take place.
Usage of bad language on my side: SFINAE's power occurs during the attempt of template argument substituition. Failing substitution leads to failing argument deduction and this again prevents template successful instantiation. Greetings from Bremen, Daniel Krügler
