That magic number "40" seems a little strange to me. 
In the example above, I used String.methods.sort, just
to get a sorted listing of the methods for "String". "ri" does a 
sorted listing, similar to the above, which can be invoked from the
command-line.

No. But then again, am not sure what you are after here. Are you trying to get
"ri"-like output from within the interpreter?
