So if I define an opAssign for a struct with void* as the parameter like so:

struct test {void opAssign(void*mynull) {}}

It works great when used in a normal assignment like so:

void main () {
        test t = null; // compiles just fine
}

but refuses to compile for function parameters with default values of null like
so:

void tfunc(test t = null) {} // nope nope nope nope


This occurs in 2.058.

It was late when I submitted this, so I wasn't thinking about what was actually
going on here.  The null assignment as a default parameter is treated as though
it were passed as an argument which would require some way to cast
implicitly....  So given that, this really becomes a feature request for
implicit casting support.
