Subject: Added special `for_each` function for iterating lists at runtime *
 i.e. we probably will want to access our compile time computed values at
 runtime sooner or later * runtime iteration using e.g. a normal _for-loop_ is
 not possible as we obviously can't dynamically insert new types into our
 templates
