+The `nodecl` pragma can be applied to almost any symbol (variable, proc,
 type, etc.) and is sometimes useful for interoperability with C:
 It tells Nim that it should not generate a declaration for the symbol in
 the C code. For example:
 
 .. code-block:: Nim
   var
-    EACCES {.importc, noDecl.}: cint # pretend EACCES was a variable, as
