No problem! It's very specific and I understand well that it certainly
adds complexity that is not needed often enough. I still believe that
having something like ByteString would boost low-level IO performance a
lot - I'll take the gem route then, I have some ideas there. Maybe I'll 
get the chance to discuss some of them with Matz at LSRC next week :)

OK, I'll open another issue for this.

Feature #6361: Bitwise string operations
https://bugs.ruby-lang.org/issues/6361#change-28587

Author: MartinBosslet (Martin Bosslet)
Status: Rejected
Priority: Normal
Assignee: 
Category: core
Target version: 


I know this has been discussed a lot in the past (and if there's still 
an open issue for this, I apologize, I couldn't find one), for example
in [1]. While it is generally no problem to implement this on the fly,
I still find that built-in support would be a real improvement. There
are quite some use cases in cryptography where this would come in very
handy, but I'm sure there are lots of other areas, too.

While of course I understand the reasons that were given in the previous
threads that ultimately lead to rejection, I still would like to reopen
the discussion as I felt that in every thread so far the consensus was
that having bitwise string operations would indeed be quite valuable.
