in reply to What does $_ = qq~"$_"~ do?

qq is the generic double quoting operator. It's "" with using different delimiters. So the line $_ = qq~"$_"~; encloses whatever text is in $_ with double quotes. It's the same as $_ = "\"$_\""; without having to escape the " characters.

    I was completely overthinking it - thanks for clarifying.

      Hi,

      There is a list for overthinking avoidance :)

      Basic debugging checklist

      perl -MO=Deparse - $_ = qq~"$_"~; __END__ $_ = qq["$_"];

      ppi_dumper is also great at hints

      $ ppi_dumper input_file PPI::Document PPI::Statement PPI::Token::Magic '$_' PPI::Token::Whitespace ' ' PPI::Token::Operator '=' PPI::Token::Whitespace ' ' PPI::Token::Quote::Interpolate 'qq~"$_"~' PPI::Token::Structure ';'
