Hi Lars:
I would have only sent intern-soft a string if it were not for the doc
string which says it takes a string or a symbol.
"Return the canonical symbol named NAME, or nil if none exists.
NAME may be a string or a symbol. If it is a symbol, that exact
symbol is searched for."
So, the doc string must need changing if your view is correct.
Bob
