Perl 6 Version:

This is perl6 version 2015.10-49-ga333147 built on MoarVM version 2015.10

OS:

Linux Mint 17.2

uname -a

Linux <hostname> 3.16.0-38-generic #52~14.04.1-Ubuntu SMP Fri May 8 
09:43:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

When I run this program with one file on the command line it works:

#!/usr/bin/env perl6

use v6;

for lines() {
   .say;
}

If I specify 2 or more files on the command line, it cats them together 
as expected, but it hangs at the end.
