Hello

I'm using 5.6.2 and got that same error. I fixed it by doing:

@b=@_;@_=@b; # then preceed as usual

I bet the problem is that you are calling the function as

score(qw/X 6 5 7 9 ...../);

instead of:

@arr = qw/X 4 5 6 .../; score(@arr);

Map is modifying the content of the list (using s#...#10#). Passing a list (constant) to the sub makes @_ elements aliases to the values passed. This is just like saying

"helo" =~ s/l/ll/;

which does not make sense.

Did I make myself clear? Does it make sense?
