Something like could works :
   return *( cast(void[]*) sqlite3_column_blob(stmt, n) ) ;

Forget my example, it's wrong.
Sorry.

void[] has a length, so you have to know the length. Assuming the length 
is n... Maybe try something like this (untested):

struct DynArray
{
     public void* ptr;
     public size_t length;
     public T[] toArray(T)() { return cast(T[]) cast(void*) (*this); }
}

void[] get_bytes(int n)
{
     return DynArray(sqlite3_column_blob(stmt, n), n).toArray!(void);
}

int i=sqlite3_column_bytes(stmt, n);
return sqlite3_column_blob(stmt, n)[0 .. i];

thanks, it works. and much simpler than i tought

In unrelated matters: if you're writing a sqlite3 binding, take a look at
tools.sqlite3. :)
