select is a very versatile construct: it waits for events, retrieves data from tables, creates a list from elements of an input list that satisfy a condition, a dropdown list element, an event for when selection changes, branches between multiple arms, conditional between two expressions, prints a text-based menu prompt in a loop, and more.
