Re: [RFC] Deprecate Backtick Operator (V2)

Hello, would say intellectually speaking I could accept the argument of time\investment\code however in reality figuring out for someone having a minimum of shell experience in that case, would figure out in 5 minutes if he is very slow minded; none the less, learning new features, new apis, that's the life of a software developer; once again there is a discussion about a mosquito with very strong arguments made about hypothetical difficulties. There are far more complex and mind challenging topics which are disregard; which would ask thoughts on the long term; in profit of minor issues thrown into the arena with no more than a 5 minutes thinking.
