[seqfan] Re: Re Nice variant on A030067

[W. Edwin Clark]

To be clear, when in a Maple procedure no RETURN or return statement is
encountered in the execution of the code, then the procedure returns the
value of the last statement executed in the procedure. That's why in the
case mentioned no "return" is needed.
I suppose this is well-known to most Maple users.
