Isn't this more transpiling than compiling?
A transpiler might read PHP and spit out C, or Java or some other existing programming language, spitting out the code for a virtual machine doesn't make you a transpiler unless you're going to argue that all compilers are just transpilers, it's like one of those "Actually goats are fish" arguments. OK, but now the word "fish" is useless so why go to this bother ?
