It's a basic information, better than no information at all. If my app tells me
a file is missing then maybe I can find it. But see below.

Adding the line number of the user code that has caused the IO exception is
handy to fix little script-like D programs.

A IO exception is meant to be caught by your large serious programs, it's never
meant to be shown to users.
