--- Comment #1 from FeepingCreature <default_357-l...@yahoo.de> --- Oh, I see. It's an issue with lazy... I've tried to fix this, and it runs into the issue that lazy, being not templated, cannot transfer call site guarantees such as @safe and nothrow into the getter function, hence breaking get()'s annotations of nothrow and @safe in a way that makes it unusable in nothrow/@safe code. And there is not even hope that DIP1033 fixes this, because the knowledge that the expression is @safe/nothrow cannot be transferred in through a function call - because the conversion to delegate happens *after* the template instantiation, and the delegate type is the first place that we could have @safe/nothrow knowledge. Damn... --
