Ok. I opened the ticket: http://code.google.com/p/pharo/issues/detail?id=1067

I replaced _ to :=  and take into considerations the henrik suggestions.

Best,

Mariano

Please also use (String new: (self size * 2)) writeStream instead of
'' writeStream.
In this case it won't lead to any noticeable performance increases,
but it's good practice anyways :)

I'd also argue the expected returnvalue of "hex" might not be clear as
something like "asHexString" when applied to a collection (hex
previously only implemented on single values), but that's a minor issue.

When looking around, I also noticed WriteStream nextPut: does an
unnecessary check for ByteStrings which is pretty ugly (plus, it
decreases nextPut: performance for all ByteString writeStreams), filed
as Issue 1065.

Cheers,
Henry
