proposal

I'd like to propose a new arithmetic operation \ (inverse division), i.e. b\a = a/b

cf. It's supported in Julia.

x \ y | inverse divide | equivalent to y / x

ref. https://en.wikipedia.org/wiki/Division_(mathematics)#Notation

motivation

It would be easy to write an expression like ans\3 instead of 3/ans. This will reduce the number of key types.

technical concern

If an escape character is needed in the future, we may consider ` (backtick) instead to avoid conflict.

cf. Powershell use backtick for escaping.
