Method chaining and the finishing problem

are there any approaches, given a statement like the following

First().Second();

to know from within First() whether/when Second() has executed?

Reference: http://marti开发者_运维问答nfowler.com/dslwip/MethodChaining.html

Second() will not execute until First() has completed, therefore this is impossible. All that First() can do is to violate fluency, thereby making it impossible for Second() to run.
