It tells me more than ABSOLUTELY NOTHING. Between the length and 
the index, I can at least get an idea of if there's a broken 
record or broken code.

It is already there, just discarded!

D's error handling does this a lot, and there's no reason good 
for it. Useless RangeErrors (a segmentation fault would be more 
helpful!), generic Exceptions with random strings instead of 
useful info, dumb crap like enforce discarding easy info. Ugh.
