This achieves the same:
template lookupTable(alias fn,uint max=255){
static assert(maxenum ReturnType!fn[max+1]
lookupTable=iota(0,max+1).map!fn.array;
}
Ha! That's .

(Though I'd never actually do template argument checking in a static
assert within the template body.)

Depending on what the usecase is, you might want to change that
to static immutable instead:
static immutable ReturnType!fn[length] lookupTable = [elements];

Does the struct have any mutable indirection? Then it is illegal.
Otherwise, can you demonstrate

Given a range with element type char, what's the best way of
iterating over it by code-point, without filling an array first?
Related to this: What's the status of std.utf and std.encoding?
The comments in std.encoding say that some functions supersede
their std.utf counterparts.

Both would work and do the same thing, but I prefer "is null"
because that is most consistent with other D code (where there
might be a difference between the two).
Alexandr Druzhinin:
In D code I do
void* data = GC.malloc(...);

void* data = malloc(...);
