Well, I do not have a possibility of another level of
indirection. I am working on a DSL embedded in D. My biggest
gripe with D is that it does not let me create a struct that
gives the end user a feeling of native data type. But on the
other hand we have a lot of capabilities that other languages
do not have. I believe presently D is the best systems
programming language to build a DSL in, but it can be easily
made much better.
I do not know how to impress Andrei and Walter. I do not even
know if they are reading this thread.

What's wrong with "pre-"initializing your data? Surely, there are
other ways to workaround your problem then having a "2-arg
postblit". C++ allows CC with a mutable arg. It's been used
*once* (AFAIK) for auto_ptr, and *that* was deemed a complete
failure.
There might be usecases were it is legitimately useful, but not
enough to warrant such a language change.
Have you tried any of the two solution I told you about? "static
opCall" emulates a default constructor pretty well.
Another solution is simply... pass by ref?
