span

fun span(start: Int = 0, end: Int = 0, ctxt: Int = 0, block: Span.() -> Unit = {}): Span

Create a Span object with specified start, end, and context values.

A Span represents a location in the source code. It's used throughout the AST to track where each node appears in the original source.

This is a Kotlin extension function. For Java, use Spans.create instead.
