    A structured instruction can consume input and produce output on the operand stack according to its annotated block type.

    A structured instruction can consume input and produce output on the operand stack according to its annotated block type.

    It is given either as a type index that refers to a suitable function type, or as an optional value type inline, which is a shorthand for the function type [] -> [valtype].
