By dsimcha:

No, it's not difficult for me to fix. It's just that I've never heard this argument against using "I" and "O" as symbols before and I've used them several times before (though I'm not sure if I've used them in Phobos) without a problem. If it's really a problem for some reason that I'm missing then it belongs in our coding standard. It's just that serif fonts are so universal in programming editors/IDEs that I have trouble believing that that the confusion you point out would ever occur in practice, and "I" is a very terse, otherwise clear symbol for a generic integer type.
