At the risk of asking something stupid, could it be both? I'm thinking of unary minus / literal negative number. (Assuming there's such a thing in Ruby as a literal negative (?))
----------------------------------------
Feature #8430: Rational number literal
https://bugs.ruby-lang.org/issues/8430#change-39476
Author: mrkn (Kenta Murata)
Status: Open
Priority: Normal
Assignee: matz (Yukihiro Matsumoto)
Category: core
Target version: current: 2.1.0
I would like to propose a new literal syntax for rational numbers.
The implementation is available in my github repository:
https://github.com/mrkn/ruby/commit/8ca0c9a53593e55d67f509fc403df616e2276e3a
This patch implements a notation that consists of an integer, "//", and another integer, in a row.
The first integer is the numerator, and the second is the denominator.
Whitespaces are permitted between them.
For example:
1 // 2 == Rational(1, 2)
1 // 1 == Rational(1, 1)
0 // 1 == Rational(0, 1)
"0 // 0" occurs syntax error.
I think this new syntax isn't conflict with an empty regexp
because this implementation doesn't treat // as a binary operator.
