Help needed for "recursive template expansion error"

[Anthony Abeo]

Hello all,

I have an Algebraic type of structs as shown below. One of the 
structs is the `Code` struct and this struct holds an array of 
ATTR_INFO. It is self-referential. Obviously the compiler is 
unable to get the maximum size of ATTR_INFO at compile-time, 
hence throwing the error. I will be very grateful for any help to 
resolve this issue.

alias ATTR_INFO = Algebraic!(SourceFile, ConstantValue, 
Excepsion, Code,
                                                     
LineNumberTable, LocalVariableTable);

struct Code
{
	size_t attribute_name_index;
	size_t attribute_len;
	size_t max_stack;
	size_t max_locals;
	size_t code_length;
	const(ubyte[]) code;
	size_t exception_table_length;
	Tuple!(size_t, size_t, size_t, size_t) exception_table;
	size_t attribute_count;
	ATTR_INFO[] attributes;
}
