    Randy,

    I will get back to the rest of your email later, but I wanted to
    respond to one item now.

    I appreciate the spirit. If this would have resolved the problem, I
    might have suggested something similar myself (even though I strongly
    dislike context sensitive lexing). Unfortunately, the keyword "config"
    is the main cause of keyword conflicts.

    In our suite of 67 real customer designs that we use for testing, "config"
    is used as an identifier in 7 designs (or 10.5%). An additional 3 designs
    (4.5%) used "cell" as an identifier. None of the other config keywords
    appeared . So eliminating all of the config keywords except "config"
    wouldn't help much.

    Changing to less-used keywords to replace "config" and "cell" would solve
    the main problem, but would not be backward compatible.
