Proposal
Currently writing a comparison expression between strings causes an error, as they generally are not considered of numeric value. However, in standard JavaScript comparing strings is allowed due to the fact that they have a codepoint value corresponding to their Ascii/UTF-16 value. Using this value, comparisons can be performed and expressions like "A" < "a" are evaluated as true given their codepoints being 65 and 97 respectively.
