    It was just a thought.

    But I still have to sum up the sizes of everything I'm gonna need
to call C_alloca, then to set bit types in the right places of the
allocated memory, the functions have a variable number of arguments
etc., etc.
    I'm not saying that this is a design flaw or something. It's just
that I'm used to write Lua extension modules, and it's even fun! But
of course Lua is only interpreted and was designed from the beginning
to be easily embeddable and extended.
    And chicken has lots of FFI features that ameliorates this
problem if one mixes C and Scheme. It's just a different way of doing
things.

Cheers,
