try

pragma(msg, typeof(__traits(getMember, vulkan_input,  
m)).stringof);

because at compile time the code generated for writeln() is not 
executed.

Also take care with the getMember trait, it will only work if the 
member is public.
(or not public but located in the module where the __traits() 
code resides).
