tech? no! man, see...Are there programming languages in which 2½ is read as a numeric rational literal?
no, more mr. nice guy!@technomancy perl6 will parse ½ as 0.5, but rejects 2½. 2 + ½ does work
@rx So close!
@technomancy also i seem to recall the factor language parsing 2+1/2 as the rational 5/2. no unicode, but true mixed fraction literals nonetheless
(note: 2+1/2 is treated as a single token; factor is stack-based so doing a runtime addition would look like 2 1/2 +)
