Not to stick my head further into the discussion at this point, but
actually, original Pascal has {...} for comments. The diglyphs (* and
*) were used on systems like Pascal 1100 in Copenhagen, where the
UNIVAC "Fieldata" 6-bit (!) character set didn't contain curlies. (We
also used (. .) for array indexing because [\] had been replaced by
Danish characters.)
