Agreed.

Feature #13626: Add String#byteslice!

----------------------------------------
It's a common pattern in IO buffering, to read a part of a string while leaving the remainder.

~~~
# Consume only part of the read buffer:
result = @read_buffer.byteslice(0, size)
@read_buffer = @read_buffer.byteslice(size, @read_buffer.bytesize)
~~~

It would be nice if this code could be simplified to:

~~~
result = @read_buffer.byteslice!(size)
~~~

Additionally, this allows a significantly improved implementation by the interpreter.
