Raku Language Handles Infinite Sequences With Built-In Tools and Lazy Evaluation

The Raku programming language offers built-in routines called 'gather' and 'take' that allow developers to collect dynamically computed values into sequences. Raku also supports the '...' sequence operator to generate potentially infinite series, such as rows of Pascal's triangle, using anonymous functions applied iteratively. The language treats infinity (Inf and ∞) as a functional value rather than an error state, enabling operations like summing an infinite range to correctly return Inf. Raku's Z zip metaoperator can pair infinite ranges together, with output naturally limited by whichever operand is finite, or capped manually using methods like 'head'. These features collectively demonstrate Raku's lazy evaluation model, where infinite structures are defined but only computed as values are actually needed.
