Channels

• channels([<delimiter>])
• channels(<object>)
• channels(<object>[,<delimiter>])

With no arguments, channels() returns the list of all channel names which are visible to the player. With two arguments, returns the list of channel names to which the object is listening, delimited by <delimiter>.

With one argument, the behavior is ambiguous. If the argument matches an object, returns the list of names to which the object is listening, space-delimited. If not, it's treated as a no-argument case with a delimiter.

If you don't have permission to examine the object, you only see those channels to which the object belong for which you have permission to join (or are joined to).
