Hello, Forth
If you want an optimized binary, you can pass extra C compiler flags to the build:
$ waforthc --ccflag=-O2 --output=hello --init=SAY_HELLO hello.fs↩
Contrary to the [standalone native WAForth](https://github.com/remko/waforth/tree/master/src/standalone), the resulting binary does not contain a WebAssembly engine, and therefore the compiler infrastructure is no longer available:
