This is only relevant if you write your own macros. If you do,
remember to add a debug declaration in them.
+
+*** The theading macros (~->~ and ~-->~)
+
+The threading macros would require special treatment to namespace
+correctly. However, you can use the ~:functionlike-macros~ keyword to
+tell *Names* to treat them as regular functions.
+
+For example, in the following snippet:
+#+BEGIN_SRC emacs-lisp
+(require 'dash)
+(define-namespace foo-
+:functionlike-macros (-> ->>)
+
+(defvar var nil)
+(defun fun (x &optional y)
+ (concat x y))
+
+(-> "some string"
+ (fun var)
+ fun)
+)
+#+END_SRC
+the ~(fun var)~ part would be namespaced prefectly fine (~fun~ and
+~var~ will be identified as a function and variable respectively),
+because it looks like a regular function call. However, the second use
+of ~fun~ will not be correctly namespaced, because that ~fun~ looks
+like a variable.
+
+In other words, you should use these macros like this instead:
+#+BEGIN_SRC emacs-lisp
+(-> "some string"
+ (fun var)
+ (fun))
+#+END_SRC
+
** Accessing Global Symbols
If one of your definitions shadows a global definition, you can still
access it by prefixing it with =::=.
"The version number given by :version.
Used to define a constant and a command.")
+(defvar names--functionlike-macros nil
+ "Function-like macros, even if their debug-spec says otherwise.
+When expanding the namespace, these macros will be treated
+exactly like functions. This means that their contents will be
+namespaced like regular function arguments.
+
+To add macros to this list, pass the :functionlike-macros keyword
+to your namespace along with a list of macro names (as unquoted
+symbols).

+
+ (define-namespace foo-
+ :functionlike-macros (-> ->> thread-first thread-last)
