need to add compile-time (BEGIN) warnings (and tests) for:

- reading ENV
- writing ENV
- using POSIX 
...

%ENV is always re-initialized at run-time.

reading ENV in a BEGIN block should do no harm, and might be actually useful, 
but we nevertheless should warn about it, as the run-time value will be 
different.

writing ENV in a BEGIN block is just ignored and we need to warn about it.

Same for using POSIX and other syscalls side-effects. readers and writers are 
just ignored.
