So it is intensionally preventing me from doing something I 
should be able to do if I want without issue because it thinks I 
will harm myself?

Why not a compiler switch that enables it? It's blocking 
something that might be an issue but is almost surely not and 
prevents the vast capabilities that it would otherwise be able to 
accomplish.

I guess one can always patch the compiler...

But Dmd does give an error about security, it usually says that 
the there are not source code available for compile time or 
something like that.
