US-ASCII is very limiting for expression. To me "for i in {1..10}" is as easy or easier to read and much faster to type. But if you grew up reading and writing code that supported and relied upon math and scientific notation in practical programming maybe you would like it better, it is possible. -- underground experts united https://dataswamp.org/~incal
