Many other languages support the concept of a range that can be any sequence that meets simple criteria, beyond just integer sequences. I was looking to use a shorthand to create a list of characters from 'a' to 'z' but ranges only supports Integers, which means I needed to do

Range.from_to_inclusive(Char"a".to_int(), Char"z".to_int()).to_list().map(Char.from_int)

This could also apply to other kinds of sequences, such as dates.
