Hello, I found somehow strange behavior when running two regexes in one function call. The original script was trying to count lines, words and chars similar way as wc does. Here is extracted snippet to demostrate: 
use Data::Dump qw{dump};

$data = do { local $/ = undef; <DATA> };

# in single call
dump [
        scalar($data =~ s/\n/\n/g),
        scalar($data =~ s/(\w+)/\1/g),
        length($data)
];

# in multiple calls
dump [  scalar($data =~ s/\n/\n/g) ];
dump [  scalar($data =~ s/(\w+)/\1/g) ];
dump [  length($data) ];

__DATA__
Line1 Word Something
Line2 Other Word

[download]
The output is this 
[6, 6, 38]
[2]
[6]
[38]

I wonder why first line is not [2, 6, 38]. Can someone help me understand this? It looks like second regex result is overwriting also the first result. This is my first post on perlmonks, sorry if I did something wrong.
