Ok, I found it. Compiling it with DMD 1.020 it gives me:

main.d(1): variable N forward referenced main.d(1): Error: Integer constant expression expected instead of N main.d(1): Error: Integer constant expression expected instead of cast(uint)N main.d(1): Error: Integer constant expression expected instead of cast(uint)N

Same as in Descent. However, compiling with DMD 1.028 it compiles ok. So we have to update to DMD 1.028 to get rid of that error. But I doubt that will happen for the net release. Probably for the next one. :-)

Temporarily, you can turn semantic errors off.

Look what I've found in mtype.c while porting to DMD 1.028:

--- if (sc->parameterSpecialization && dim->op == TOKvar &&

((VarExp? *)dim)->var->storage_class & STCtemplateparameter)

{

/* It could be a template parameter N which has no value yet:

  • template Foo(T : T[N], size_t N); */

return this;

} ---

:-)
