// ErrorReplier is an optional function that allows changing how the error
// is replied. It overrides ReplyError and is only used for MessageCreate
// events.
//
// Note that errors that are passed in here will bypas FormatError; in other
// words, the implementation might only care about ErrorReplier and leave
// FormatError as it is.

// EditableCommands when true will also listen for MessageUpdateEvent and
// treat them as newly created messages. This is convenient if you want
// to quickly edit a message and re-execute the command.
