Struct Outcome 

pub struct Outcome {
    pub value: Option<Array>,
    pub shy: bool,
}

What a run produced: the value of the last sentence, and whether a session would display it.

A SHY value is one an APL session keeps to itself: the answer of a definition that came from an assignment. The value is the same either way — it flows to whatever consumes it, is assigned, is printed by a caller that asks — and only a caller that displays results unasked needs the flag.

Fields

value: Option<Array>

None when the last sentence yields no value at all: an assignment, ⎕←, a definition of a name.

shy: bool

Meaningful only where there is a value; false for J, which has no shy results.
