Nor is there anything bad about this:

auto x1 = templateFunctionWithComplicatedReturnType("a");
auto x2 = templateFunctionWithComplicatedReturnType("b");
auto x3 = templateFunctionWithComplicatedReturnType('c');
auto x4 = templateFunctionWithComplicatedReturnType("d");

in fact, it lines up neatly so I prefer it :P
