My opinion is ---

Known by their names, Perl's builtin functions are low-level
functions as thin wrapper of system calls.  Their results are not
straightly connected to result of each test unit.  Programmers
should write the code to decide what result is allowed and/or
disallowed.

In short, "early" check [1] of result is required to make test unit
working expectedly.

autodie warns this obvious fact, without giving any suggestions
how we should do.  I feel it is, at least for our project, not
desired.


[1] Note that "early check" includes ignoring results.  For example,
  we usually need not checking result of close() (of course we may
  do, but gain little).  However, in some cases we evidently should
  check, such as when we closed pipe.  It is also we who decide
  whether result should be checked or not, not only it is expected or
  not.
