10	Cannot declare anonymous union around generic type	Thierry Delisle	mlbrooks	"Minimal example:
{{{
forall(otype T)
struct result {
    #ifdef THE_ERROR
    union {
    #endif

    T value;

    #ifdef THE_ERROR
    };
    #endif
};
}}}

produces : 
{{{
error: ‘_sizeof_Y1T’ undeclared here (not in a function)
}}}


Desired for:

{{{
forall(otype T, otype E)
struct result {
	bool has_value;
	union {
		T value;
		E error;
	};
};
}}}
