I like the way Ada ends its statements. However, as said in the
chapter about the revised syntax (tutorial), we took the option not to
end the statements with a keywork ("end", or "fi" or things like
that), in order to show that all of that is functionnal.

When you see:
      if e1 then e2 else e3 end

you don't have the impression that e2 or e3 are *results*: the "end"
gives you the impression that everything is terminated. Often, newbies
don't understand the functional way this statement must be read. If we
change the syntax with this "end", it is going to be more difficult to
explain then.

This way, I regret a little bit the "do { }" of the "for" loop. A
"do .. done" would have been more logical (same for "while").
