Trompe

Trompe is a strongly-typed scripting language with type inference. This is developed for handy scripting to clean up chores, which enables quick startup, interpretation (no need build configuration), and detecting type mismatch errors easily and quickly.

Current version is pre-pre-pre-alpha. See examples/ for more detail.
