This Is Just to Say

I have translated
the program
that was in
the translation units

and which
you were probably
expecting
predictable results

Forgive me
they required no diagnostic
so undefined
and so erroneous

I originally wrote this around April 2nd 2018 and then tweeted it.

As I noted in the tweet almost all the replacement words came from the defintion of undefined behavior in the C++ standard:

undefined behavior
behavior for which this document imposes no requirements
[ Note: Undefined behavior may be expected when this document omits any explicit definition of behavior or when a program uses an erroneous construct or erroneous data. Permissible undefined behavior ranges from ignoring the situation completely with unpredictable results, to behaving during translation or program execution in a documented manner characteristic of the environment (with or without the issuance of a diagnostic message), to terminating a translation or execution (with the issuance of a diagnostic message). Many erroneous program constructs do not engender undefined behavior; they are required to be diagnosed. Evaluation of a constant expression never exhibits behavior explicitly specified as undefined in [intro] through [cpp] of this document ([expr.const]). — end note  ]
