MAIN Sub

[Bottoms, Christopher A]

Hello all,

As soon as I add the MAIN sub to my module file, my test file complains:

Method 'chars' not found for invocant of class 'Failure'
  in 'Cool::substr' at line 2365:CORE.setting
  in 'process-cmd-args' at line 7414:CORE.setting
  in  at line 7492:CORE.setting
  in 'MAIN_HELPER' at line 1
  in main program body at line 
1:/home/cbottoms/workspace/Rakudo/Impute/lib/MaizeDiversity/Impute.pm


I'm not sure if I'm doing something wrong, or if it is simply an implementation 
issue. I' m using Rakudo Start from January 2011, running on Fedora 7 GNU/Linux 
(64-bit).  Any ideas? Below is the code I'm using. 

# Module File
use v6;

sub MAIN ( $arg1, $arg2 ) {
return 1;
}

# End of Module File


# Test file:

use v6;
use Test;
BEGIN { @*INC.push('/home/cbottoms/workspace/Rakudo/Impute/lib'); }

use MaizeDiversity::Impute;

# End of test file


Thanks,

Christopher Bottoms

In your module file, after the "use v6" line, add this line:
module MaizeDiversity::Impute;

Hope this helps,
