The -e1 is unnecessary.
That seems to be because perl sees the 'e' in 'foo e eval...' as an -e command line switch. Change it to something else besides 'e' and the behavior changes.
It sort of feels like the same sort of exploit one should worry about when using the two-arg open unsafely, passing user data to a database without placeholders, or instantiating user data as variable names.
