Why does perl omit the "at line xxx" when I supply a "\n" at the end of a warning?
Example: 
b3n@sdf:~> cat test.pl
#!/usr/bin/perl

warn "foo";

warn "bar\n";
b3n@sdf:~> perl test.pl
foo at test.pl line 3.
bar

This appears to be the same for both perl 5.6.0 (eww) and 5.8.7 (specifically perl, v5.8.7 built for alpha-netbsd-thread-multi)

Is this to allow for exception handling with objects or something similar? I'm assuming this is expected behaviour, but I didn't see any note of it in the warn() perldoc page. I won't lose any sleep over it, but it did strike me as odd.
Thanks
Update: added perl version(s)
