Hi,

   Was able to resolve the above issue, but again getting the same 
for other lines such as below when i tried to add the appender.

auto CleanDirlst = appender([]);
CleanDirlst ~= PVStore[1][i].to!string.split(",");


Error: cannot implicitly convert expression appender([]) of type 
Appender!(void[]) to string[].
