Dear PerlMonks, I would like to ask for your wisdom once again. I want to create a program which will open a file, read all its lines into an array and find words whihch they have 4 or more consonants in the row. I created the following program but I have in my terminal all the words (it's like grep is not working). 
#!/usr/bin/perl -w

use strict;
use warnings;

open(MYFILE, "fil") || die "$!";
my@fil=<MYFILE>;
close(MYFILE);
chomp(@fil);

my@outcome=grep(/[bBcCdDfFgGhHjJkKlLmMnNpPqQrRsStTvVwWxXzZ]{4,}/, @fil
+);

print @outcome, "\n";
