This was very helpful -- your code is very readable, and combined with
Petko's code, helped me with the solution.
Turns out that Petko's idea basically worked -- except doing an unset on
an entire array causes the array to become undeclared, which SDV then
sees as not there and so sets the usual default values. Setting to an
empty array worked.
So I combined these approaches with an ROS pattern to get the final
solution. Needs more testing, but for now seems to work great.
$PmFormPostPatterns = array();
'<split', '/\\(::\\w[-\\w]*:(?!\\)).*?::\\)/s', '');
'/(\\(:: *(\\w[-\\w]*) *:(?!\\))\\s?)(.*?)(::\\))/s';
"(::myvar:$1::)"; //assumes myvar is the last in the list.

Thanks very much for offering suggestions -- I wouldn't have made it
without them :)
