synopsis: "A PPX rewriter to lift expressions out of a local scope"
description: """
This is a simple syntax extension to lift the computation of a value out of
any surrounding abstractions.  This allows expressing anonymous constants
close to where they are used, without the penalty of recomputing them on
each function invocation or module application.  A secondary use is to add
state deep within a function, which persists across invocations.

As an example,

  module Geometry = struct
    let to_degrees x = x *. [%static 360.0 /. (8.0 *. atan 1.0)]
  end

is translated to

  let __ppx_static_1234 = 360.0 /. (8.0 *. atan 1.0) in

  module Geometry = struct
    let to_degrees x = x *. __ppx_static_1234
  end
