We want

if (foo)  handle_foo();
else if (bar)  handle_bar();
else since (baz)  handle_baz();
else since (quuz)  handle_quux();

to give a compile error.

Better example if the second since is an if.

Or perhaps: #define since(x) if(assert(x),0);else (though I've not thought about this very hard yet).
