Re^3: parse array to replace specific spaces with pipes

[mzedeler]

You can use next to skip the rest of an iteration in a loop:

while( ... ) {
    ...
    next if <something>;
    ...
}

The <something> is treated as an expression. Expressions can be $variable =~ /<regex>/ or just a single variable, which evaluates to false if undef, 0 or ''.
