Thanks, seems that using dataPoints[] makes dataPoints usable as an

how is this documented in DList.
dataPoints is an aggregate type variable, not a range and slice operator

Then something that just allowed you to do:

this compiles:

auto stack = SList!int();

Hello!
Is there a convenient way to get rank of range a.k.a. count of
dimensions in compile time? Like:
static assert( rankOf!(uint[]) == 1);
static assert( rankOf!(uint[][][]) == 3);

Please submit a bug report. The compiler may be able to abbreviate
