If you hit the Library, under Perl Functions, Alphabetical, you'll find ucfirst() and lcfirst(), which will upper- or lower-case (respectively) the first character of a given word. So you could do something along the lines of: 

my @array = qw( foo bar foobar barfoo 1 2 3 );

foreach my $i (0 .. $#array) {
    $array[$i] = ucfirst($array[$i]);
}

I suspect a regex in this case is actually overkill.... HTH....
