# errretur-y.tst: yash-specific test of the errreturn option

# Many test cases in this file use the "! ( ... )" pattern because it would be
# otherwise impossible to distinguish the behavior of errreturn and errexit.

# An expansion error in a non-interactive shell causes immediate exit of the
# shell (regardless of errexit), so expansion errors should be tested in an
# interactive shell.
