Oh. No, the "combined" statement would look like this:
try:
cmd.append(path)
call(cmd)
except Exception, e:
raise CmdException(str(e))
finally:
os.unlink(path)
It works exactly like the nested try...finally and try...except
statement above, but results in less indentation---and would thus be
preferred, if not for the 2.4 compatibility issue.
