So a script I wrote long ago has stopped working somewhere between perl 5.x and 5.22.
myscript.pl 
#!/usr/bin/perl
use strict;

while (<>) {
# do stuff with each argument given and spit out a sting.
# this example I'll just do
print;

}

Now when I run it 
$> ./myscript.pl foo bar baz
Can't open foo: No such file or directory at ./sp2comma.pl line 13.
Can't open bar: No such file or directory at ./sp2comma.pl line 13.
Can't open baz: No such file or directory at ./sp2comma.pl line 13.

The expected result is of course 
$> ./myscript.pl foo bar baz
foobarbaz

Has something happened? Why is while (<>) not doing what it use to? How do I get the old behavior? Thanks in advance.
