First, how is that "giving myself an excuse"? Second, it's a total non sequitur, and even then, it's a day old has it broken?
Bugs are normal software development.
Changing syntax and breaking things make work for everyone else for the convenience of developers. Reliability is what makes a tool a tool.
How else might one explore a new language (vapour) in the open among interested like-minded developers seeking to iterate on a tool found lacking (R)?
Changing and iterating things makes.
What part of this is giving any sense of stability? It's clearly an experimental language, so I find it hard to understand why you are discussing stability and compatibility at all.
