Using bash, it should work if the first line of the perl script is

#!/path/to/perl -perl_switches

but otherwise you'll get 'name-file.pl: print: command not found' for the 
first perl command (print for instance) that bash doesn't recognise.

You should have said so in your first email, your suggestion will not
always work with bash. 

BTW which shells can execute such a script without the first identifying
line?
