Well, the way I now want to use it (never know about the future) is
that it is a small file (below 1 KB) and I want to use all the lines.

At the moment all the lines except the last in the same way. But that
properly will change. For example beginning a line with {l}, {r} or
{c} would mean that the line should be left justified, right justified
or centered.

Agree, no use converting a dictionary to an array, if you can loop
over both. ;-)

At the moment I leave the code alone. Done enough with it. But I am
still interested how you would do that? Just to learn the language.
And who knows: when my usage changes, it would maybe become a good
idea to implement it.
