How to check for the type of a template parameter?
...e is_same:
#include <type_traits>
template <typename T>
void foo()

...f a client side function executed this code:
// AJAX code to display the "foo" state goes here.

lemons && document.write("foo gave me a bar");
Personally, I'll often use single-line if without brackets, like this:
