Let's put it this way: if a programmer insists on using a font where l, I, 1, O, 0, etc. have the slightest chance of looking like each other, then that programmer is not one we'd want in the D community.

I promised Derek to not put down a certain programming language, but let's just say, that anyone with a history of C (or C++), can't in their worst nightmares, imagine using a font that doesn't make a difference between 0, O, 1, l, I,,, etc.

Having said that, I don't have a specific opinion about what Walter was thinking of.

I certainly prefer a font that distinguishes them. But arial and helvetica don't, are very common, and tend to creep in by default.

What about if they are using an IDE with support for 1 font only?

I would tell them to get a new one.

ROTFLOL ... I went so far as to create a variety of Courier that changed the lowercase L to look like the lowercase T (t) but without the bar, and put a dot inside the Zero glyph to make it distinguishable. If anyone wants it just let me know.

Or one of these:  http://www.proggyfonts.com/

ProggyCleanSZ.  THE font.  For everything.

Consolas nicely distinguishes between the letter O and the number 0. As do DejaVu Mono and Monaco.

It's just a shame Consolas isn't widely available yet (and requires ClearType to do it justice - which is fine by me, I can't stand looking at a screen without ClearType turned on anyway).

Huh? Doesn't Courier New already distinguishes between the two?
ilIL0O -> all look different.

Not for people who run 1600+ resolutions. (myself and others I'm sure) Bitmap fonts such as these just dont scale well.
