This is a very different style than what I have seen in the past. In the past,
most examples of flex tend to match against the tokens as individual items and
return immediately so that bison can do the grammar check and generation. So in
my existing (semi-working) .l, I followed this style and produced:
FOR { return FOR; }
...
TO { return TO; }
Then over in my .y I have:
FOR variable '=' expression TO expression
Using your method, what would the associated bison look like? Just a single
item matching the entire line?
