For such things, Gwydion currently throws a <simple-error> with an 
appropriate message/format string and arguments.

Possibly.  Why?  What would you do with it?

If you're catching the error close to where it is generated then why not 
just change the code so that it tests the index, or uses element("", 0, 
default: something)??

If you're catching the error a long way from where it is generated then 
why do you care exactly what the error was?  What are you going to do 
about it?
