If the CSV record is written as:


... then you're right - any decent CSV library should read that as two 
strings. BUT...


... should be read as two ints - there are no quotes, so the CSV reader 
*should* assume that these are two numbers, not strings.

As for the automatic detection, I'm also against it. That's why some support 
for column names and types when reading/writing tabular data should be part 
of the spec.

p.s. I'm using Excel and I'm not ashamed of it. Should I ? :-)
