[1 of 1] Compiling Main             ( prog.hs, prog.o )

prog.hs:3:11:
    Ambiguous type variable `t' in the constraints:
      `Num t' arising from the literal `42' at prog.hs:3:11-12
      `Typeable t' arising from a use of `typeOf' at prog.hs:4:35-43
    Probable fix: add a type signature that fixes these type variable(s)
