This was kind of an annoying change to make since 0.11.0 has issues
where it will point to the wrong srcloc on compile errors in generic
code (which this 100% is) fortunately fixed in master. The motivation
for this change is that the arg vector already contains 0-terminated
strings, so we can avoid a lot of copies. This makes forwarding
command-line arguments to C-functions that expect zero-terminated
strings much more straightforward, and they also automatically decay
to normal slices.
Unfortunately, environment variable values are NOT zero-terminated, so
they are currently copied with zero-termination. This seems to be the
fault of Windows/WASI, both of which already are performing
allocations (Windows to convert from UTF-16 to UTF-8, and WASI to get
a copy of the environment). By duplicating the std EnvMap
implementation, we could make a version that generates 0-terminated
env vars without extra copies, but I'll skip on doing that for now.
