} Doesn't work for me:
Hrm. I was sure I'd tried it, but on your input I get the same result
you do. Well, there's always:
IFS=';' eval 'fields=( $=dataline )'
However, it occurs to me that with dataline='...;";";...' -- that is, a
quoted semicolon in the input data -- there's no quick solution that's
going to do exactly what you need.

}
} Yes, I didn't do it because I had hope to one day do a block move
} via arrays. Also, reading to a parameter first makes it easier to do
} some pre-processing like quote removal, otherwise I have to do it
} field by field after reading.

} This makes the program more cumbersome to write and read because all
} variables become quite long-named...
So don't name the array "fields", name it "f" or some such. Three extra
characters (e.g. $f[capital] instead of $capital) for a whole lot less
complexity elsewhere. And quote removal may be as easy as:
f=( ${${(kv)f#\"}%\"} )
(Whether it's actually that easy depends on your input data, e.g., you
might also need to convert \" to ", but I think `read' will have done
that for you already.)
