Could the "bytes" type be just the same as the current "str" type but without the implicit unicode conversion ? Or am I missing some desired functionality ?
No. It will be a mutable array of bytes. It will intentionally resemble strings as little as possible. There won't be a literal for it.
Thinking about it, it may have to offer the search and replace facilities offered by strings (including regular expressions). Here is an use case : say I'm reading an HTML file (or receiving it over the network). Since the character encoding can be specified in the HTML file itself (in the <head>...</head>), I must first receive it as a bytes object. But then I must fetch the encoding information from the HTML header: therefore I must use some string ops on the bytes object to parse this information. Only after I have discovered the encoding, can I finally convert the bytes object to a text string. Or would there be another way to do it?
