First, I'd like to separate the whole sw stack in a few layers:
    - hw interactions (aka low-level code typically programmed in asm in C-based
    - kernel code (first-class system-wide abstractions)
    - system code (services/abstractions hurd builds on top of any kernel it is
      using as a substrate)
    - other software (mainly user applications and daemons)

So now, my question would be which features you don't like of a specific
language (C in this case), and in the context of which "layer"?

Not that I'm very knowleadgeable in BitC (I'd say I have no knowledge at all),
but I'm curious of which are the itches you want to scratch, and more important,
which are they tradeoffs.

Of course, analyzing the tradeoffs would require an agreement on a list of
quantifiable features and their relative weight.
