Enum ControlStrictness 

pub enum ControlStrictness {
    Lenient,
    Strict,
}

How strictly a control structure reads what it is given.

The lenient reading is the one both languages ship: a condition is true where its first atom is, whatever else it holds, and a :Leave outside a loop leaves the definition. Dyalog reads both strictly — a condition is one element and no more, and :Leave belongs to a loop — and says so rather than answering. GNU APL has no control structures at all, so nothing it records turns on this.

Variants

Lenient

The first atom decides, and a stray :Leave is a return.

Strict

Dyalog: a condition is a single value, and :Leave needs its loop.
