I believe that Algol 68 loops looked like the following (in somewhat more
[for <identifier> [from <suite>] [step <suite>] to <suite>]
do <suite> od
where either "for" or "while" had to be present. Note that in Algol 68, the
value of a "suite" (which I think they called a "serial clause") is the
value of the last expression in it.
