First, the message: Hello, world! A simple test follows: ${message} A more rigorous test, showing that we're not faking it: ${message@#$%&}

Message exists! ...and even generates output! Nested statements are ok, too.

Here's more edge cases of if instructions. One is not two And more complex ifs: And again: One is one Now for switch case instructions: The world says hello to you. And another one, with a default instruction: This is no message in particular Another, degenerate switch: This is not a switch statement. A list literal test: abc def ghi A boolean test: B1: False B2: True Now call the function: Variables are: 1, 2, 3. test23 Hello, world! hello all one hash89 output Simple.
