Loop through it and allocate each one rather than trying to do it in a

What about this?
as[] = new A();

Oh pardon the constructor I was playing with as a learning

Thanks.
for DMD -O :

immutable foo = sqrt(2.0);
pure float precalculated()

return foo;

For GDC the answer is yes:

Yes, it is lazy, so it only calls toString when the result is
actually used (by the join call).
In case you do need to create an extra list

You can shorten this by using std.conv.to. Also keep in mind that
