Having only added the semicolon to the bar
script. My copies were exactly
as you posted them.
Just for fun. Here's the output from my session:
Can't exec "./foo": No such file or directory at ./bar line 3.
Unknown 'strict' tag(s) '-1' at ./bar line 3.
BEGIN failed--compilation aborted at ./bar line 3.
Ahh, sure enough. No semicolon on line 2 -- gotta love that -w
I am ./foo ()
Looks good. Lets try it as intended
devel# ./bar 123
I am ./foo (123)
I think I can safely reply now. :-)
Evil is good, for without it, Good would have no value
