Subject: [ruby-core:49399] [ruby-trunk - Feature #7322] Add a new operator name  #><  for bit-wise "exclusive or"


Issue #7322 has been updated by david_macmahon (David MacMahon).


I fully agree that repurposing '^' to be a power operator is not a good idea.

One alternative idea that might not make anyone happy would be to create a new power operator "^^" that is the same as "**", but seems more like exponentiation to those too young to know (or too old to remember :-)) Fortran.

Please feel free to ignore this suggestion,
Dave

I propose to alias (({Fixnum#^})) and (({Bignum#^})), which stand for bit-wise "exclusive or", with a new operator name (({#><})).

Is it necessary to go along with C, Python, and Mathematica?
According to Wikipedia ( http://en.wikipedia.org/wiki/Exclusive_or#Alternative_symbols ), the "^" symbol is not used for XOR outside of programming context.

Here are some examples of mathematical notation: http://mathworld.wolfram.com/XOR.html (there are also examples in the Wikipedia article).

The Unicode symbol is "���".

If eventually (({Fixnum#^})) as XOR is deprecated, this will liberate this symbol for other uses, for example for all kinds of exponential notations (for me, "a^n" usually means "the n-th power of a").
