so why this? it seems to take a long time from the last import 
xxx semantic3 xxx to reach this

inline scan grasshopper
inlined   std.datetime.systime.SysTime._timezone =>
           std.datetime.systime.SysTime.opAssign!().opAssign
inlined   std.datetime.systime.SysTime._timezone =>
           std.datetime.systime.SysTime.opAssign!().opAssign

can not be avoided? i need only till semantic, no care in inline 
et cetera
