I was trying out one of those grammar checking programs the other day.
It came upon the expression "not at all" in my document and issued
the following advice:
"not at all" -- Wordy expression. Consider "not" or "by no means"
instead.
I chose to ignore this sage counsel, especially the second part.
Then, later in the document, the program said:
"by no means" -- wordy expression. Consider "not" or "not at all"
instead.
