That would _complicate_ the language (by adding a rule).  I repeat what
I've already stated repeatedly: a good criterion for deciding which good
practices a language should enforce and which ones it should just
facilitate is _language simplicity_.  If the enforcement is done by
adding rules or constructs it's probably not worth it; if the
"enforcements" is done by NOT adding extra constructs it's a double win
(keep the language simpler AND push good practices).
