... &&= too techy ...

A bit too techy and, for these old eyes, just plain difficult to see! I think I'd incline toward something like (all untested)

sub fred {

    my ($t, $u, $v, $w, $x, $y) = @_;
    
    somelogger(5, "fred", "start of fred");
    
    my $ok = 1;
    $ok = method1($t) if $ok;
    $ok = method2($u) if $ok;
    my $pid = open my $ph, "/somewhere/program $v |";
    my $output = '';
    $ok = method3(<$ph>, \$output) if $ok;
    close $ph;
    waitpid $ph,0;

    if ($ok) {
        somelogger(5, "fred", "fred completed successfully");
        }
    else {
        somelogger(5, "fred", "error during fred");
        }
    
    return $ok;
 
    }

or maybe even (assuming the methods can be made to return error strings or the empty string for no error)

sub fred {

    my ($t, $u, $v, $w, $x, $y) = @_;
    
    somelogger(5, "fred", "start of fred");
    
    my $err;
    $err = method1($t) unless $err;
    $err = method2($u) unless $err;
    my $pid = open my $ph, "/somewhere/program $v |";
    my $output = '';
    $err = method3(<$ph>, \$output) unless $err;
    close $ph;
    waitpid $ph,0;

    if ($err) {
        somelogger(5, "fred", "error '$err' during fred");
        }
    else {
        somelogger(5, "fred", "fred completed successfully");
        }
    
    return $err;
 
    }

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
