Why are const strings used in templates for compile time found in exe

[js.mdnq]

The following code

http://dpaste.dzfl.pl/64025e0a

when compiled, has all the static and const char[] strings used 
only for compile time inside the executable.

How to prevent this?

specifically I'm talking about

static const char[] __ClassNameFix = "_A!("; static const char[] 
__NestLevelFix = "_NestLevel";

and all the mixin strings from the templates. They all show up in 
the executable but are only used for static compilation.
