That was a problem for me today XD . Couldn't make a auto 
fct(string[] choices ...)(string[] id, string[] key ...) but I 
managed to find a workaround...

// KEYWORDS
enum USING = "USING.",
	VAR = "VAR.",
	LIST = "LIST.",
	SET = "SET.",
	ZSET = "ZSET.",
	HASHMAP = "HASHMAP.",
	LOCK = "LOCK.",
	UNLOCK = "UNLOCK.",
	SKIPCACHE = "SKIPCACHE.",
	INCREMENT = "INCREMENT.",
	DECREMENT = "DECREMENT.",
	FRONT = "FRONT.",
	BACK = "BACK.",
	PUSH = "PUSH.",
	POP = "POP.",
	REPLACE = "REPLACE.",
	TRIM = "TRIM.",
	RETURNS = "RETURNS.",
	LENGTH = "LENGTH.",
	EXISTS = "EXISTS.",
	VALUE = "VALUE.",
	KEY = "KEY.",
	STREAM = "STREAM.",
	ERROR = "ERROR.",
	

void exec(string command)(){
	foreach(str ; choice.splitter(".")){
		writeln(str);
	}
}

void main()
{
	exec!(USING ~ VAR ~ ADD ~ USING ~ LIST ~ INSERT ~ LOCK)();
}
