(i. 5 5) writecsv 'foo.csv'
120
fread 'foo.csv'
"0","1","2","3","4"
"5","6","7","8","9"
"10","11","12","13","14"
"15","16","17","18","19"
"20","21","22","23","24"
Also, I was long under the impression that literal data in a csv file
should be quoted but apparently this is not the case. It's hard to say for
sure as there is no real spec for this format, and I don't remember what
disabused me of this notion (perhaps taking the behavior of Excel as the
paradigm?)
