20synopsis: "Inlined Function Composition"
21description: """
22`ppx_compose` is a simple syntax extension which rewrites code containing
23function compositions into composition-free code, effectively inlining the
24composition operators. The following two operators are supported
25
26 let (%) g f x = g (f x)
27 let (%>) f g x = g (f x)
28
29Corresponding definitions are not provided, so partial applications of `(%)`
30and `(%>)` will be undefined unless you provide the definitions.
31
32The following rewrites are done:
33
34 * A composition occurring to the left of an application is reduced by
35 applying each term of the composition from right to left to the
36 argument, ignoring associative variations.
37
38 * A composition which is not the left side of an application is first
39 turned into one by η-expansion, then the above rule applies.
40
41 * Any partially applied composition operators are passed though unchanged.
42
43E.g.
44
45 h % g % f ==> (fun x -> h (f (g x)))
46 h % (g % f) ==> (fun x -> h (f (g x)))
47 (g % f) (h % h) ==> g (f (fun x -> h (h x)))"""
