 Since argument evaluation order is not specified by the C programming language, this scheme is built to work regardless of evaluation order.
-The first time a unique expression is executed, the actual expression is evaluated and the accompanying boolean is set to true.

 Every subsequent evaluation of the unique expression then results in an access to the stored result of the actual expression.

 Thunks 0 through 3 provide wrappers for the @otype@ parameters for @const char *@, while @_thunk4@ translates a call to @print([int, const char *])@ into a call to @print_variadic(int, [const char *])@.
 This all builds to a call to @print_variadic@, with the appropriate copy construction of the tuple argument.
