As a hobbyist I love seeing new languages. I look at their features and a few simple examples and immediately imagine they'll solve all the issues I have faced with other languages. I generally appreciate the massive amount work that goes into something like this. But when I want to work on a project, I am wary of using something new. I just know in my heart I'll set the wrong flag on the compiler and the binary will end up in a directory I can't find and it'll take me two days to figure out how to do it. My question is this: if the main strength of this language is that uses Swift-like syntax, and lets you develop native apps in Android and iOS, why not just make an Android compiler for Swift?
