This is not doing what you think it's doing. The syntax t => { 
return t; } is equivalent to t => () => t. That is, it's 
returning a function that takes no arguments, not a value.

For that very same reason, if you compile and run your code 
without -betterC, only the first printf() will be executed, and 
only one line of output will be generated.

What you should do instead is:
     T!((t){
             printf("test 2 name = %s\n".ptr, t.name.ptr);
         }, "test");

(note the lack of the => arrow)
