In fact, if the amount of data you want to keep is greater than the one 
you want to throw away, it might be better to make the buffer immutable 
and allocate new buffers as you go forward. One allocation per buffer 
is likely going to be less wasteful than one allocation + one copy per 
string (+ some space wasted after each memory block).

If you don't intend to keep most of the data after parsing however, 
then you should go for a mutable buffer and copy what you need.

What I like very much about Andrei's proposal for a buffered input 
range is that it makes it supports equally well mutable and immutable 
buffers.
