Don't they disable writes to code segment anyway?

I don't think the OP was talking about self-modifying code in
that sense. I think he was talking about a program that
modifies its own *source code*, which is a different thing than
a program that modifies its own machine code while that machine
code is running.

Yeah, that's what I mean. Basically D's meta programming
accomplishes the same effect for the most part but it is somewhat
limited. Mainly since one can't write to files for "security"
reasons(I'd like to know of any real world security issues that
this has caused!).
