In 2.8.0/Windows Vista: When 'unique' gives a type error message, it prints out even if errors are being caught:
> try(unique(quote(hello)),silent=TRUE)
hello
This comes from the .Internal unique routine:
> try(.Internal(unique(quote(hello),NULL,NULL)),silent=TRUE)
hello
I guess it is using the internal equivalent of print rather than the
internal equivalent of stop.
