[virtmach] Inferno Dis VM Questions

[Murray, Peter C]

I finally got around to looking at some of the Inferno references (thanks
rog@vitanuova.com for posting the links here).  Of course, now I have a
couple of questions :) 

Why are so many type conversions (eg. big to str, byte array to str, etc)
and various string operations (eg. insert char into str) part of the byte
code specification and not implemented as library routines?

(Maybe I should join Inferno mailing list and ask questions there?)

Thanks,
- Peter.
