- *
- * to turn it into a series of individual calls like this:
- *
- * PART #winbot :m00!
- * PART #darkgalaxy :m00!
- *
- * The seperate calls are sent to a callback function provided by the caller
- * (the caller will usually call itself recursively). The callback function
- * must be a command handler. Calling this function on a line with no list causes
- * no action to be taken. You must provide a starting and ending parameter number
- * where the range of the list can be found, useful if you have a terminating
- * parameter as above which is actually not part of the list, or parameters
- * before the actual list as well. This code is used by many functions which
- * can function as "one to list" (see the RFC) */
+/* LoopCall is used to call a command classes handler repeatedly based on the contents of a comma seperated list.
+ * There are two overriden versions of this method, one of which takes two potential lists and the other takes one.
+ * We need a version which takes two potential lists for JOIN, because a JOIN may contain two lists of items at once,
+ * the channel names and their keys as follows:
+ * JOIN #chan1,#chan2,#chan3 key1,,key3
+ * Therefore, we need to deal with both lists concurrently. The first instance of this method does that by creating
+ * two instances of irc::commasepstream and reading them both together until the first runs out of tokens.
+ * The second version is much simpler and just has the one stream to read, and is used in NAMES, WHOIS, PRIVMSG etc.
+ * Both will only parse until they reach Config->MaxTargets number of targets, to stop abuse via spam.
