16       Long identifiers, used in parsetree.

18       Warning: this module is unstable and part of Compiler_libs .
19
20       To  print  a longident, see Pprintast.longident , using Format.asprintf
21       to convert to a string.

42
43       For a non-empty list l , unflatten l is Some lid where lid is the  long
44       identifier  created by concatenating the elements of l with Ldot .  un‐
45       flatten [] is None .

56       Deprecated.  this function may misparse its  input,  use  "Parse.longi‐
57       dent" or "Longident.unflatten"
58
59
60       This   function   is   broken   on   identifiers   that  are  not  just
61       "Word.Word.word"; for example, it returns incorrect  results  on  infix
62       operators and extended module paths.
63
64       If  you  want to generate long identifiers that are a list of dot-sepa‐
65       rated  identifiers,  the  function  Longident.unflatten  is  safer  and
66       faster.  Longident.unflatten is available since OCaml 4.06.0.
67
68       If you want to parse any identifier correctly, use the long-identifiers
69       functions from the Parse module, in particular Parse.longident .   They
70       are  available since OCaml 4.11, and also provide proper input-location
71       support.
