It's kind of amusing, after all this time, to look at the documentation for 
a CPU instruction and see it described in terms of VHDL instead of just prose.

  That was certainly random.

It just goes to show that nowadays, people design CPUs using VHDL. Waste not 
want not.

Also, open prose might be subject to interpretation when complexity
kicks in, whereas VHDL can be seen as a simplified and explicited prose.

And VHDL allows you to run the instruction set on an emulator, without
wasting resources to translate the prose.

Perhaps we should all just communicate in VHDL then.

Remember the movie about "Captain, My Captain" (a notion of circle and
lost poets...) usual languages are mainly for seduction (and beyond),
but that's a part CPU and mathematicians are not interested in.

"Would you like to get in and have a drink ?" is not an offer for just a
drink...

In spoken language, the fact that you mentioned something sometimes 
carries as much significance as the thing you mentioned.

For a quick experiment, try saying to somebody "you're going to die". 
They all act as if this is some kind of great revelation, rather than a 
mundane self-evident fact. Which is kind of amusing - until the beatings 
start...

"So... why aren't we doing what Jack Sparrow said?"
"Because it was Mr Sparrow who said it."
"...do you think he wasn't telling the truth?"

Compare:

"OH MY GOD, WHAT ARE YOU DOING?!"
"Oh, wait, you were /actually/ just going to give me some lemonade?"
"YUHUH!"
"Oh, right. Let me get dressed again..."

  Sometimes such inferred (or interpreted) extra meanings can cause all kinds
of misunderstandings and controversies. (Just google for "elevatorgate" for
a rather iconic recent example.)

This is absolutely true. Consider the following conversation:
