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: 

devel# ./bar
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.

devel#

Ahh, sure enough. No semicolon on line 2 -- gotta love that -w :-) 
devel# ./bar
I am ./foo ()

Looks good. Lets try it as intended 
devel# ./bar 123
I am ./foo (123)

devel#

I think I can safely reply now. :-)
