range
Creates a range of numbers, which can also be iterated through.
The behavior of an open range is delegated to the consumer. For instance, using a left-open range with forEach will make the loop start from 1.
The difference between this function and the built-in .. operator is that the latter does not allow for dynamic evaluation, hence both ends must be literals. This function allows evaluating ends dynamically: for instance, .range from:{1} to:{.sum {1} {2}}.
Floating-point numbers are truncated to integers.
