@ -32,7 +32,7 @@ Moving the end position can go through `Move(int)` which also accepts negative i
When the internal `io.Reader` returned an error, `Err() error` will return that error (even if subsequent peeks are still possible). If `Peek(int) byte` returns `0` when an error occurred. `IsEOF() bool` is a faster alternative than `Err() == io.EOF`, if it returns true it means the internal buffer will not be reallocated/overwritten. So returned byte slices need not be copied for use after subsequent `Peek(int) byte` calls. When the `io.Reader` provides the `Bytes() []byte` function (which `Reader` does in this package), it will use that buffer instead and thus `IsEOF()` returns always `true` (ie. copying returned slices is not needed).
## Lexer
Lexer is an improvement over Shifter in that it does not need the returned byte slices to be copied. Instead you can call `ShiftLen() int`, which returns the number of bytes that have been shifted since the previous call to `ShiftLen`, and use that to specify how many bytes need to be freed up from the buffer. Calling `Free(n int)` frees up `n` bytes from the internal buffer(s). It holds an array of buffers to accomodate for keeping everything in-memory. If you don't need to keep returned byte slices around, call `Free(ShiftLen())` after every `Shift` call.

The `MoveTo(int)` function has been renamed to `Rewind(int)` to fit its meaning better. Also `Bytes() []byte` has been renamed to `Lexeme() []byte` for the same reason.
