Reconstructing a method piecewise from meta::source

[jcelerier]

Hello,
Given for instance

struct(my_metaclass) TheClass {
   [[some_attributes]]
   template<typename A, std::size_t N, typename... Args>
   static constexpr inline auto foo(A a, int arr[N], Args&&... args) 
     /* cv-qual if not static */ 
     /* & / && if not static */
     noexcept(noexcept(false)) 
    -> decltype(a) try {
     return 0;
   } catch(...) {
     return 1;
   }
};

what would be the metaclass code (if possible) that given a meta::info corresponding to foo, would allow to recreate foo exactly as it is - but not by doing -> the_meta_info;, instead by reconstructing it piecewise (in order to have a starting point to make modifications on it).

thanks !

just having a starting point to do this with

struct(my_metaclass) TheClass {
   int foo(int x) { return x + 1; }
};

would already be great (context is, I'm trying to see how much one could reimplement noexcept purely with injection)
