**Source:** [`atloria-monorepo/libs/parser-core/src/parsers/backend/go-control-flow.ts`](https://github.com/sherkety/atloria/blob/main/atloria-monorepo/libs/parser-core/src/parsers/backend/go-control-flow.ts#L149)

Read the guards and recover blocks out of a span of Go source.

`startLine`/`endLine` are 1-based and inclusive, and are how a caller scopes this to one
function; the lines reported back are absolute, so they point into the file the reader opens.

```

## Parameters

| Name | Type |
