The following code examples are valid as of Nim 0.10.2. Syntax and semantics may change in subsequent versions.

This example shows many of Nim's features, one of the most exotic ones is the implicit <code>result</code> variable: every procedure in Nim with a non-void return type has an implicit result variable that represents the value that will be returned. In the for loop we see an invocation of <code>countdown</code> which is an iterator, if an iterator is omitted then the compiler will attempt to use an <code>items</code> iterator if one is defined for the type that was specified in the for loop.
