There is no conflict here.  You must always reference a record component this
way.  I think any other way would be less elegant.

At least an Ada compile will tell you about conflicts.

You can't use reserved words for anything else.  I have also wanted to use Exit
at times, but settled for Quit or Stop or some such.  Range is another reserved
word that would be the best variable name in some cases.  You just have to
qualify it in some way - Maximum_Range for instance.
