Upon running a program of mine, it crashes with the (very helpful) message:

"Error: Error: conversion"

Can anybody tell me what kind of statements could cause such an error? A 
line number would have been nice, of course, but I doubt a new version 
incorporating this will turn up today :).

Also, is it possible to have line numbers printed for AVs?

And ArrayBoundsError (Exception...) isn't very exact for the case where 
you try to do
arr[m..n]
when m > n and (0 <= m,n < arr.length).

Well, found it. I was trying to toInt a zero length string. The error 
message was somewhat terse, though.

I agree it can be hard to understand. I haven't run into this particular problem
before, but I see how it would be confusing.

The error message actually includes the invalid string, but in this case the
invalid string is "invisible". 


Perhaps, we can change line 22 on std\conv.d from

to


It would help in this case and probably others, too.


Here's the code I used to observe the problem:

#import std.conv;

#void main()
