Each line specifies a possible legal argument list.  For example, the line:

> Fixnum Zero

specifies that it's legal to provide two arguments, the first a
Fixnum, and the second Zero.  This line:

> Real Real Real *

specifies that it's legal to provide two or more arguments of type
`Real'.  Of course, in this case the last case subsumes all of the
others for the purposes of this particular error, so it should be the
only one displayed.
