AFAIK, it's not exactly the same thing, as int(10) would be only a constructor,
so would not downcast.

Writing:
//----
void foo(long k)
{
  int n = int(k);
}
//----

Would fail to compile the same way as:

//----
void foo(long k)
{
  int n = k;
}
//----

would. You'd need to use:

//----
void foo(long k)
{
  int n = int(cast(int)k);
}
//----
