I've never had to install C. It always comes on my computer.
NO. A programming language is something abstract. Something that exists inside your head. Like an idea. You can't install a concept on a computer. Just programs.
And if you conflate programming languages and the tools that work with them, you're creating a lot of confusion.
Simpler naming leads to simpler communication. Is all I am saying.
You're spot on. It's simpler to have different names for different things. A language is not the same as a compiler for that language. Therefore we have different names for the language and for our compilers.
In Perl 5 it doesn't matter very much if conflate the language and compiler, because there's just one compiler, and so context usually makes it clear which one you mean. That's not the case with Perl 6, Haskell, C, and many other languages.
