I don't understand your reasons at all:

Why do you want/need an undef or nil object in language where everything has
a value? And where you have immutable data?

Many complain about the if *expression* but I don't really understand why it
warrants so much interest. I personally find that I don't use it much
anyway, and that because I don't *need* to use it. I find that having
pattern matching has changed my style of coding. I just checked my code for
LFE and I found that where I most use a "tradional" if is is my checker
module where I only check and don't produce anything.

I honesty don't see how this can make it difficult to write libraries. I
have written quite a few and that was not the problem in writing them.
