 def arange(start, stop=None, step=1.0, repeat=1, infer_range=False, name=None, dtype=None):
     """Returns evenly spaced values within a given interval.
 
+    Values are generated within the half-open interval [`start`, `stop`). In other
+    words, the interval includes `start` but excludes `stop`. The function is
+    similar to the built-in Python function `range` and to `numpy.arange`,
+    but returns a `Symbol`.

     Parameters
     ----------
-    start : number
+    start : number, optional
 
 Review comment:
   Why modify it? It seems start doesn't have default value, but stop has one (None)
   
   Edit:
   It is coincident with NumPy.
