Awk without regexps makes little sense;

I think this comes down to what is a regular expression and what is not a regular expression.

mind that the basic syntax of Awk programs is described as
   pattern  { action }

I'm guessing that 40-60% of the awk that I use doesn't use what I would consider to be regular expressions.
    (NF == 5){print $3}
    (NF == 8){print $4}
Or:
    {total+=$5}
    END{print total}
I usually think of regular expressions when I'm doing a sub(/re/, ...) type thing or a (... ~ /re/) type conditional.  More specifically things between the // in both of those statements are the REs.
Maybe I have an imprecise understanding / definition.
