You're slightly misreading the description. Have a look at the simple
example below:
>> try [1 / 0]
** Math Error: Attempt to divide by zero.
** Where: 1 / 0
>> error? try [1 / 0]
== true
>> error? err: try [1 / 0]
== true
>> probe err
** Math Error: Attempt to divide by zero.
** Where: 1 / 0
>> err: none
== none
>> error? try [err: 1 / 0]
== true
>> probe err
none
== none
Note that there is a difference.
