Exercise 12.3 (P341)

Implement the missing cases of the encode function. Encode booleans at t and nil, floating-point numbers using Go's notation, and complex numbers like 1+2i as #C(1.0 2.0). Interfaces can be encoded as a pair of a type name and a value, for instance ("[]int" (1 2 3)), but beware that this notation is ambiguous: the reflect.Type.String method may return the same string for different types.
