I have a case like :

I have a factory method, I am creating some instances given 
some enums.
My question is about :


void PushIntoVector( BaseEnum[] baseEnumList )
{
     Base[] baseList;
     foreach ( tempEnum; baseEnumList )
     {
        baseList ~= Factory(tempEnum);
     }
}

I don't want to use "foreach" loop. Is there any cool std 
function that I can call ?

Something like baseEnumList.CoolStdFunc!( a=> Factory(a) 
)(baseList);

so basically it becomes:

Base[] baseList = baseEnumList.map!(el => Factory(el));

there's also a parallel version of map [0] if you ever need to 
map the list concurrently.
