How about having more detailed Error messages?

1) ArrayBoundError: add the bad index

current:
# extern (C) static void _d_array_bounds(char[] filename, uint line);

suggestion:
# extern (C) static void _d_array_bounds(char[] filename, uint line,
# size_t badIndex);


2) SwitchError: add the uncaught value

current:
# extern (C) static void _d_switch_error(char[] filename, uint line);

suggestion:
# extern (C) static void _d_switch_error(char[] filename, uint line,
# void* badValue, TypeInfo badValueType);

Good idea.

 suggestion:
 # extern (C) static void _d_switch_error(char[] filename, uint line,
 # void* badValue, TypeInfo badValueType);


Feels dicey. What would the switch error print or do with the values? What 
if the badValue was a temporary value on the stack that just became invalid 
because of the throw?

Good question.

 What if the badValue was a temporary value on the stack that just became
invalid 
 because of the throw? 


I guess it would have to make a copy of the value.

An alternative would be to make _d_switch_error a template function....
