Initial Release

Features

• Map cases to results.
• Map multiple cases to the same result.
• Refer from one case to another by ref-ing its index.
• Refer from one case to another by use-ing its when value.
• Leverage the lazy nature of functions to compute a result only when needed, and not at the time of the case declaration.
• If a function is intended to be returned as is, it can be put under the eager key.
