class Lazy<A>

package interlude.ds

@:directlyUsed@:nullSafety(Strict)@:publicFields

Delays evaluation of a value until access to it is needed

var delayed = expensiveOperation.toLazy();
trace(delayed.toString()); // 'Lazy<>'
var expensiveResult = delayed.eval();
trace(delayed.toString()); // expensiveResult

Returns:

true if l has already been evaluated
