/**
 * @assertion StackTrace current
 * Returns a representation of the current stack trace.
 *
 * This is similar to what can be achieved by doing:
 *
 * try { throw 0; } catch (_, stack) { return stack; }
 * The getter achieves this without throwing, except on platforms that have no
 * other way to get a stack trace.
 * @description Checks that this property can be called and contains not null
 * value
