Other persons said so but it should be noted that it is no longer
completely true. RFC 4034 (published in march 2005) says:

   Because every authoritative RRset in a zone must be protected by a
   digital signature, RRSIG RRs must be present for names containing a
   CNAME RR.  This is a change to the traditional DNS specification
   [RFC1034], which stated that if a CNAME is present for a name, it is
   the only type allowed at that name. 

Mixing CNAME and A is still forbidden but you cannot say "Never use
CNAME with other types" any more.
