in thread Help with regex for complicated key=value string

$esc is never used in your code, so that means "\\," is not handled yet.

but without doing strict error-checking like yours

It's not really. It only checks for 'key=,...' (key with no value) and 'v"alu"e' (invalid quoting).

Because only alphanumerical keys are allowed anyway (I didn't mentioned that before, sorry) there is no need to look for escaped '=', etc., i.e. everything which doesn't start with /\s*[\w_]+=/ is taken as a single key-less value.

That's the same strategy I used, but I didn't limit to alphanum chars. To do so, change
/\G ( [^=,]+ ) = /xgc && ( $key = $1 );
to
/\G ( [a-zA-Z0-9]+ ) = /xgc && ( $key = $1 );

    $esc is used: 
            if ($esc) {
            $esc = 0;
        }
...
        elsif ( $char eq '\\' ) {
            $esc = 1;
        }

    and "\\," is handled quite well in my tests.

    Do I miss here something?

      Nevermind. I wrongly thought 
              if ($esc) {
            $esc = 0;
        }
...
        elsif ( $char eq '\\' ) {
            $esc = 1;
        }

      was identical to 
      ...
        elsif ( $char eq '\\' ) {
        }
