I think |myList| would be a good idea.  I'm planning to allow | x | to 
be
used for the absolute value of an integer or float, so perhaps | x | 
could
be a general operator to give the "magnitude" of an expression:

| myList |   -> length of list
| myInt |    -> absolute value of int
| myFloat |  -> absolute value of float
| myVector | -> length of vector
| myString | -> number of characters in the string [?]
