if a symbol is marked extern(CT) delete it before it passed to 
the linker, or some other stage of processing; and lets see what 
happens.

I think youd get an optimizing tool, improve metaprogramming for 
betterc and speed up compilation when you know the symbol is 
metaprogramming nonsense such as `std.StaticMap`

That's the third time this shows up:

I really hope that somebody could take a look on that and users 
could start benefitting with that ASAP

I kinda think people were thinking about it wrong; isn't it just 
something that effects "mangling"

```d
extern(C) foo()=>3;
enum int bar=foo;
```

compiles, so isnt it an extern thing?

In my head theres a list of extern mangling functions that 
magicly defines whatever mangleof is, and CT could just be a very 
very dumb one

`extern` is also used to specify the used calling convention.
I feel like this feature should rather be a `pragma` instead.

Maybe something along the lines of `pragma(emitCode, false)` or 
`pragma(codeGen, false)`?
