Since iota is a template doesn't that mean it's not in phobos.lib 
but rather generated and built into my application?  I'm not 
compiling in release mode so I would think any bounds checking it 
had would remain (I haven't yet looked at the source to see if 
there are any checks).  I can definitely see stripping any bounds 
checking from a release build, of course.

Doing this same thing to a slice of an array does throw a Range 
Violation exception in release (and asserts in debug).
