I'll start by saying that I didn't actually try out your code. That 
said, I think what you're seeing is the same issue I reported and 
explained in the link below, together with workaround. I never got an 
answer to that post, however...

The workaround is to use apply1 instead of apply in the placeholder 
expression. Try this,

     typedef apply1< plus< _, int_<10> >, _ > t2;

Best regards,
