Agreed. I have this test too in AFIO, plus I cycle that test for 
everything headers only, AFIO headers only but ASIO not headers only, 
ASIO headers only but not AFIO headers only, and finally nothing 
headers only. I also cycle having one of the TUs use variadic 
templates and the other TU not. The reason for the dilligence is that 
I take advantage of inline virtual support/bug/misfeature when the 
compiler just happens to support it for headers-only builds, plus I 
keep forgetting to update the non-variadics support :( There is 
plenty of scope for unenforced errors to leak out if a CI doesn't 
help me.
