Is there a way to extract the correct typeinfo of an array if

Nope, typeinfos are only stored in runtime on classes. All
other types get it only through the static info.
Consider the following:
char[10] a;
char[] b = a[3..5];// from the middle of it
void* c = b.ptr;
Even if the info was stored with a, the slice would have no
idea where to find it, so you couldn't get it from the pointer
either.
The way druntime does it with void pointers is to pass the
typeinfo too:
void useArray(void[] a, TypeInfo a_type);
Ah thank you. :)
