Function builtinFlatMapArray

builtins.go:352–359

builtinFlatMapArray is like builtinFlatMap, but only accepts array as the arrv value. Desugared comprehensions contain a call to this function, rather than builtinFlatMap, so that a better error message is printed when the comprehension would iterate over a non-array.

(i *interpreter, funcv, arrv value)

// than builtinFlatMap, so that a better error message is printed when the
// comprehension would iterate over a non-array.
func builtinFlatMapArray(i *interpreter, funcv, arrv value) (value, error) {
	switch arrv := arrv.(type) {
	case *valueArray:
		return builtinFlatMap(i, funcv, arrv)
	default:
		return nil, i.typeErrorSpecific(arrv, &valueArray{})
	}
}

func joinArrays(i *interpreter, sep *valueArray, arr *valueArray) (value, error) {
	result := make([]*cachedThunk, 0, arr.length())
