I think you missed a big part here, the by default of purity. It is in
D more
work to enforce purity of functions then not.
I think optional purity is pretty powerful. You can have the advantages
of either, at your choice.
Absolutely. But whether purity should be the default or not is orthogonal
to this.
I would have preferred opt-out purity to opt-in, but it's not exactly
make or break.
