My exploration in corelinux in not yet comprehensive. It is a new world to
me, let alone the framework (clfw) and the library loader (clfll). All
these three tracks are interesting to me, but I'll continue my exploration
in the corelinux world first.

In the task list I found that #11180 and #11325 are unassigned.
I'll take care of #11325 first, it has been past due for > 1 year :-)

The parser "project" looks cool too, I'm sure Christophe will enjoy
working on it.

I have one thought about the metaclass for templated classes.
I see the that DEFINE_METACLASS (...) might have to include the template
type name. So, my idea is to add another DEFINE_... macro. But we also
have to consider the number of template formal parameters. Perhaps, we
could use several of these macros

   DEFINE_TEMPLATE_METACLASS1 (classname, tmpl1)
   DEFINE_TEMPLATE_METACLASS2 (classname, tmpl1, tmpl2)
   DEFINE_TEMPLATE_METACLASS3 (... , ...  , ...  , ...)

[probably we have to limit how many template parameters will be allowed.
Refer to how the STL defines only AdaptableGenerator,
AdaptableUnaryFunction, and AdaptableBinaryFunction]

Along with this, the Lisp-like meta declaration probably has to include
some way of conveying the meta template parameter?

Examples:

template<typename T1>
class A {
  DEFINE_TEMPLATE_METACLASS1 (A, T1);
...
};

template<typename X, typename Y>
class B {
  DEFINE_TEMPLATE_METACLASS (B, X, Y);
  ...
};

Will this work?
