The module vs. let scope is also interesting. Allen said the literature favored the latter but that wasn't clear from my nowhere-near-comprehensive reading.
Presumably that is a large part of our motivation for providing lexically scoped let/const/function/class rather than the semi-global function scoping.
True for bindings but not clear for private/friend visibility
qualifiers. Other languages do not all block-scope those, more the
reverse: class or package/library scope.
I believe the main arguments against implicit declarations are:
1) they catch misspelling inconsistencies (but not consistent misspellings)
Good parenthetical point (and one near and dear to my heart, probably
yours too ;-).
2) they prevent unintended share via coincidental common name selection
You mean the allow unintended sharing?
Yes, private prefixes and declarations are more powerful. Main questions
I see Kevin raising are usability and overkill. Say we reject "overkill"
for good reason. We may still have usability woes. 'private' is seven
long letters, eight with the space after.
