I want to add a static opCall with no arguments to simulate a nullary-argument constructor.
Please don't do it unless you have a _very_ compelling use case.
As nullary static opCall doesn't conflict with a nullary constructor (as the latter can't exist), it would be useful to allow it. Otherwise, how can we wrap the construction of a class with a nullary constructor?
It has never worked properly (opCall never got called) and being a bad style going against language design rationale it was completely banned. More info: https://issues.dlang.org/show_bug.cgi?id=12124
I believe CTFE-only default struct constructors should be allowed instead but until this becomes an option, having factory functions is the way to go ("auto var = unique(new T)" vs "Unique!T var = new T")
I am pretty sure many D users will disagree though :)
