I have a simple Perl script that reads some input variables from a text file. The variables are a comma separated list. I want them in an array, but I only know how to read them into a scalar and then split them. Is there a way do this in one step?

Here's some simple test code, I am playing around with:

opendir  (DIR, ".") or die "$!";
my @files = grep {/conf.*?\.txt/}  readdir DIR;
close DIR;
print"\nNo input files found.\n" if scalar(@files)==0;

foreach my $file (@files) {
  my $content = do { local( @ARGV, $/ ) = $file ; <> } ; 
  print "parsing $file...\n";
  my ($inc_vals)=$content=~/inc_vals=(.*?)\n/
  my @inc_vals=split(/, /, $inc_vals) unless $inc_vals=~/^\s$/;
}

foreach my $value (@inc_vals) {
    print "$value\n";
}

If it's relevant, I am using Strawberry Perl 5.10.1 on W7 x64.
