int and long

But for some reason can't compare struct to int using opEquals and opCmp. How
to fix it? And should it? One can write `v==intp(42)` or `v<intp(43)`.

Have you tried to overload opEquals and opCmp for ints? That seems to
work just fine for me:

     bool opEquals(int v) const { return value == v; }
     int opCmp(int v) const
     {
         return value>v?1:value<v?-1:0;
     }

Just add those to the intp struct.

It writes
Error: function strongintp.intp.opEquals type signature should be const
bool(ref const(intp)) not const bool(ref const const(short) v)

Hmm... may be my compiler version is old and this was fixed...

According to bugzilla, yes.
