In http://play.golang.org/p/RoelsmSVrI, this statement yields two errors:

  _ = []byte{"foo"}
  // cannot convert "foo" to type byte
  // cannot use "foo" (type string) as type byte in array element

One seems like plenty.  

FWIW, a similar pair of errors is emitted for other types T in []T{"foo"}.

Comment 2:

It yields two errors only for string and raw string literals where T can be of any type.
two errors:
  []T{""}
  []T{``} 
one error:
  []T{string("")}
  []T{string(``)}
  []T{true}
  []T{complex128(1)}
  []T{true}
  []T{string(0x266c)}
  []T{float32(0.49999999)}
  []T{0.49999)}
