Someone pointed out that the syntax could be confused if a constructor takes
a pointer to its own class as argument. I had originally a different syntax
but changed it just before posting thinking the new one was more consistent.
Duh! Never change a post without thinking... The original syntax had the
keywords in the calls:
static A a2 = static new (88,91) A;
...
A a4 = auto new (88, 91) A;
Now I believe it is a whole new syntax without possible confusion...
