# union types. However, outputs (eg check_call return) and class attributes
# (eg TimeoutError.cmd) we prefer to annotate with Any, so the caller does not
# have to use an assertion to confirm which type.

# For example:
#
# try:
#    x = subprocess.check_output(["ls", "-l"])
#    reveal_type(x)  # Any, but morally is _TXT
# except TimeoutError as e:
#    reveal_type(e.cmd)  # Any, but morally is _CMD
