To clarify: you can just comment out the lines near the top of interpret.c that
displays the error message about typesafe variadics. But then you find that it
doesn't compile, because it's trying to modify a global variable __arrayArg1.
(The CTFE error messages make it a lot easier to understand what's happening
<g>).
Something similar happens with struct constructors, and I think it's wrong.
It's more difficult to know how to fix it without breaking something else.
