Re: *features*

[Christian Lynbech <chl@tbit.dk>]

I like *features* because it allows a higher-level description of a
feature than `defined?'.

Consider the example of r4rs vs. r5rs. *features* is a simple and
generic way to record such a compliance level, where there really
isn't any particular function to check.

Defined? certailyn has its merits and places but *features* allow you
a freedom that defined? just doesn't have.
