Good morning. I have looked at ocamlopt and it looks very useful. Are there any plans to include macro expansion in ocamlopt? I mean something like merging the functionality of ocamlopt and pa_macro but without the restrictions that pa_macro places on where the macro can be used. Besides conditional compilation - to try different variants of the code or to have debugging messages which can be switched off without any performance penalty - I would also like to use it for short pieces of compile-time generated code (for speed up). Currently, I use a Python-based templating system em.py (http://www.alcyone.com/pyos/empy/) for this purpose. This works but combining the way Python and Ocaml syntax is sometimes not very intuitive. It appears that a modern and universal tool for compile-time code generation is MetaOcaml. However, is there a way in MetaOcaml to generate the code just once and not every time the program is run? I mean, can the code fragments be cached - saved into a file (a shared library?) and later retrieved?
