Here's a Maple trivia question: There is a Maple symbol that cannot be used as a procedure parameter. As far as I can tell it is the only one. What is it?

In the following code, why is B returned unevaluated?

restart:
A:= a:  B:= 2:
F:= _a-> eval(`if`(A,B,C), a= _a):
F(true);
                               B
eval(B);
                   ...

How does one view the Maple code that controls embedded components in a worksheet? I've looked at every menu on the toolbar and every context menu I could find, but nothing seems to fit.

Is there any way to detect programmatically that a WARNING has been issued? A method that converts WARNINGs to errors would be acceptable.

"Your Unread Contributions" is broken as of the updates made to MaplePrimes yesterday. It now simply lists every thread that I've contributed to since the update even though I've actually read all the most-recent activity in those threads.

I wanted to add this as a Comment to the "Updates in MaplePrimes" thread, but I can't do that either.
