Ah, you can't. But, again, what are you trying to do? Re- compiling your software for each implementation seems like a perfectly reasonable thing to do, given the differences between them.

Recompiling my software will not save a function created by the software at runtime.

...

Which is a different problem than the one solved by dynamic linking. Again, why do you want to do this?

I think they are not as different as you think they are.

...

I think they're very different --- dynamic libraries can be built by running the compiler, whatever you're asking for can't.

...

More generally, dynamic libraries are supported by every production-quality compiled language in existence; I know of no language that can do what you're asking for.

...

I think, again, that what you really want is a reason to discredit Haskell.

A simple question:

Can you write the value of x to a file where x = (1:x) ?

At this time, I am completely uninterested in serving as a source of your personal amusement. When you can convince me that continuing this discussion will be of use /to the Haskell community/, I will until then, goodbye. jcc
