I want to: do { prompt for and read user input } while (input is invalid) and then yield valid input. Can I do this without var in Scala?

@dibblego@michaelneale@puffnfresh That's a bit sensationalist isn't it? I've got thousands of for/yields in prod, is my app broken too?
@jroper @michaelneale @puffnfresh No, it is a mundane fact. No need to draw sensationalist conclusions from it.
