Hello,
I will soon get to work on typed allocators; I figured there
will be some issues percolating to untyped allocators that will
require design changes (hopefully minor).
For starters, I want to define a function that "obliterates" an
object, i.e. makes it almost surely unusable and not obeying
its own invariants. At the same time, that state should be
entirely reproducible and memory-safe.
* floating point numbers: NaN, or some ridiculous value like
F.max / 2?
NaN would be semantically the right thing and there even is the
concept of "signaling NaNs". I do not know how it works out in
practice, though.
