Less typing even with autocomplete is a benefit. Once you know its meaning, that both are relative to file access, you won’t have to look it up. Also, just noticed this, when I type multiword keywords in an email program or chat program autocorrect butts in. This is of practical value because much work is done in chat and email programs. </div><div class=""><br class=""></div><div class="">Simpler is better if it sufficiently conveys the meaning and it does in this case.

Also, if we decide later that scoping to namespaces is desired these same already reserved keywords give us more flexibility than the more specific keywords would allow. Internal/external could refer to the namespace scope rather than the file scope if it is inside a namespace (this is beyond the scope of the proposal but trying to think ahead). By not explicitly stating the scope you gain flexibility </div><div class=""><br class=""></div><div class="">- Paul</div><div class=""><br class=""></div></body></html>
