I just came across this recently and I haven’t used it much but it looks like it could save me a bit of time, not to mention not having to downloading compilers. C, C++, C#, VB, Java, Python, PHP, Ruby, Rust, Go and even, wait for it…BASH (no debugging of Bash yet, though) plus even MORE! Give it a shot for your quick and dirty projects or just to try something out.
