Ok, so of those 9000 programming languages how many use it for shell execution? So far I’m aware of PHP, Perl, Ruby and Shell. I would argue that this means those (first three) languages likely have a common inspiration from Shell, not that the feature is “common” amongst programming languages. > Arguing that non-universality would be the reason to remove syntax from > PHP is like arguing we should remove the use of whitespace because some > languages have significant whitespace (like Python) and you can't google > whitespace (especially if you don't know the word "whitespace") so > clearly this is super-confusing and should be removed. > Again, I wasn’t saying non-universality was “the reason” to remove the syntax. My point was that if *you* claimed it’s “common” amongst programming languages - and ignored that it’s used for *other, less dangerous* constructs in many more languages than it’s used for shell execution. > I don't mean this as a personal criticism on the RFC author, who clearly > took some thought about it and is entitled to his own opinions, but > arguments like this look a bit ridiculous to me.
