No need to discuss this in detail, but IMHO the main benefit of infinite  
lookahead
is that it allows to build a generic parser for forward ranges.
If you have only input ranges you need to handle buffering within the  
parser.

Of course it's opportune to simply read in a complete source file as  
string given their
typically limited size. It also has the benefit of avoiding additional  
string copying.
