Overview ¶
Package hook is the untyped injection slot behind internal/macroexp. It exists only to break an import cycle: macroexp's attach helper is typed in terms of *lisp.LVal, so macroexp must import lisp — which means lisp cannot import macroexp to inject the helper. Both packages instead meet here, in a package that imports nothing: lisp's init stores the helper as an untyped value, and macroexp's init recovers the typed function from it (import order guarantees lisp initializes first, since macroexp imports lisp).
Nothing outside lisp (writer) and macroexp (reader) should touch this package.

var Attach any
Attach holds a func(v *lisp.LVal, name string, callSite, defSite *token.Location, args []*lisp.LVal, id int64) stored untyped. It is set by package lisp's init and consumed by package macroexp's init.
