Fairly sure that's not relevant.

As I understand, @disable does not make a symbol invisible to the compiler, it
makes it so that invoking it (one way or another) becomes forbidden. So,
annotating the constructor with @disable will not make it prefer the static
opCall.

I suppose that, as an enhancement, the compiler could be made to prefer the
static opCall when the constructor is present but disabled, but this is likely
to complicate the language/implementation for very little gain, especially
considering that the simple workaround of writing a factory function (as the
error message suggests) is available.

Note that if you give the opCall method arguments (e.g. `static S
opCall(int)`), the code is accepted, so the problem occurs only with the
questionable ambiguous S() syntax.

As this was filed and has been inactive for over 3 years ago, I'll close this,
but feel free to reopen if you disagree.
