(* *) for comments was actually pretty commonly used - maybe because it
stands out more than { }. I don't know if I've ever seen (. .) instead
of [ ].

C also has alternative rerpresentations for characters not in the common
subset of ISO-646 and EBCDIC. However, the trigraphs are extremely ugly
(e.g ??< ??> instead of { }). I have seen them used (on an IBM/390
system with an EBCDIC variant without curly braces) and it's really no
fun to read that.
