As to your assertion of discrimination against Greek: my point was that mathematical notation *already* discriminates against speakers of Greek by appropriating their alphabet for its own purposes, so if you want to enable a mathematical-notation language mode it's already difficult to support a Greek localization. (I do wonder how modern Greek mathematicians deal with this....)
This made me curious... so hunting around on the internet I found: http://el.wikipedia.org/wiki/%CE%8C%CF%81%CE%B9%CE%BF which, although almost the same as mathematics in English (notice 'epsilon' being used in the same sense), uses 'nu' as a variable to index over the integers, and 'lambda' as a upper/lower bound. Also I found a list of abstracts (mixture of English and Greek): http://users.uoa.gr/~apgiannop/pcma08/program-print.pdf which again looks almost the same as English mathematics (especially when they write it in English), although it seems like 'lambda' is being used as a variable with rather high frequency.
