incompatible types compile error

[Maurizio Cimadamore]

The problem is that, since you are using Comparable (note the absence of 
type-parameters) you are effectively triggering an uunchecked conversion 
there - the result would be that the erased signature of 'into' will be 
used instead - that is, the return type of into will be simply 
Destination - not the type inferred from the argument - hence the 
incompatible types error.

Btw - I'm getting the error for both versions of the example you sent.
