Though it should be pretty obvious what the program does, I will explain the syntax: statements which are not indented are executed when the program starts. Indentation can have any Nim code text commented out inside this with no indentation restrictions. yes("May I ask a You can also use the discard statement together with long string literals to create block comments:
