I like to have a folder called playground within my projects, where I build related prototypes and try out new ideas. Whenever something seems to work well, I do some sort of cherry-picking to keep the things I got right within the prototype and rewrite everything else. This helps me to validate ideas while keeping the main project in good shape. It is not as extreme as choosing a different language for the prototypes, but for me, it worked well so far.
