ArrayConstructorExpression

public ArrayConstructorExpression(Expression expression,
 ExceptionMetadata metadata)

Curly array constructor: array { expr }. Each item produced by the expression becomes a singleton member.

ArrayConstructorExpression

public ArrayConstructorExpression(ExceptionMetadata metadata)

Empty array constructor (curly or square with no members).

ArrayConstructorExpression

public ArrayConstructorExpression(List<Expression> memberExpressions,
 boolean isFixedSlotsArrayConstructor,
 ExceptionMetadata metadata)

Square array constructor: [ E1, E2, ... ]. Each expression becomes a separate member whose result (possibly a sequence) is preserved.
