c7966920a6 Rewrite the documentation for most of anaphoric
Arguably, it's still not great. It's perhaps more terse than would be helpful. My goal for now is just to make sure that it's correct, and that it doesn't mislead with e.g. suggestions that these macros support only true lists, instead of arbitrary iterable objects.

8a83d0c1ea Fixes #1605: remove macros ap-pipe and ap-compose
Anaphoric macros do not work well with point-free style programming, in
which case both threading macros and `comp` are more adequate.

e4a7b317e1 Make fn work like lambda and remove lambda (#1228)
* with-decorator: Allow a `setv` form as the form to be decorated

This feature is of dubious value by itself, but it's necessary to allow `defn` to create a lambda instead of a `def`.

* Make `fn` work the same as `lambda`

That is, allow it to generate a `lambda` instead of a `def` statement if the function body is just an expression.

I've removed two uses of with_decorator in hy.compiler because they'd require adding another case to HyASTCompiler.compile_decorate_expression and they have no ultimate effect, anyway.

In a few tests, I've added a meaningless statement in `fn` bodies to force generation of a `def`.

I've removed `test_fn_compiler_empty_function` rather than rewrite it because it seems like a pain to maintain and not very useful.

* Remove `lambda`, now that `fn` does the same thing
