</div>And I guess that 4) it has various external dependencies (at least the<br>
current implementation), 5) performance might be affected because of<br>
the dynamic function lookup per call :) But indeed for portability<br>
it's the best target currently...</blockquote><div><br></div><div>None of these are absolutely unsolvable. Your design choices for structures could be ported to the CFFI backend so that it no longer relies on function calls to access foreign data, but rather creates C-INLINE forms. The same thing could be said about foreign functions. But this needs somebody to sit and carefully study how to modify CFFI to add these improvements -- and whether it is actually possible or changes in the API/semantics are required.</div>
