Here's how it would look in my library:
compressed := original zipped.
"There is currently one definition, in
AbstractStringOrByteArray, covering [ReadOnly]ByteArray,
[ReadOnly]String and its many subclasses,
ByteBuffer,StringBuffer, Substring, [ReadOnly]ShortArray,
[ReadOnly]MappedByteArray, and some others. This relies on
_ asByteArraySize and _ asByteArrayDo: _. There is no need for
a separate #utf8Encoded, that's what asByteArrayDo: *does*."
copy := original class unzip: compressed.
"This is a little trickier, but not hugely so. There is no need
for special case code. [ReadOnly][Mapped]ByteArray and ByteBuffer
are
sequences of bytes, Stringy things are Unicode, and
[ReadOnly]ShortArrays are treated as UTF16."
As far as I can tell, this just works for the original use case.
