Hello everyone,

I found a use-case where it would be useful to have constexpr functions
that are not marked as constexpr and
my question, at the moment, is if it would be technically feasible to have
something like that.

My use case is in the context of games, but it could be in other places.

Problem:

During game development it is very important to have fast iteration, so
scripting languages are often used.
At the end, when the game is delivered, I would like to have everything,
even code scripts, embedded into the
executable.

I could embed the scripts and compile at runtime, keeping the strings in
the code files.

But you could go a step further: compiling scripts at compile-time through
metaprogramming.
If I want to do this, I have to replicate an already written API, usually
in C.

For example, it would be nice in Lua or Squirrel, to be able to use these
functions as constexpr to embed the bytecode directly.
Otherwise, if you want to achieve this effect, you have to basically
reimplement everything only because the original API
won't work at compile-time.

Is there any chance that something like this is technically feasible?

Regards
