A strawman fallacy is not another way of saying "Dammit, you just made a 
counter-argument that I cannot argue against."

On the other hand, false accusations of "strawman" are a form of 
poisoning the well.


As the old legal saying goes:

"When the facts are on your side, argue the facts. When the law is on 
your side, argue the law. When neither are on your side, pound the table."

And when you can't pound the table, accuse your opponent of committing 
the strawman fallacy.

I don't forget history, I just know when it is relevant and when it isn't.

Rustom, I don't care if you want to compare Python to mathematics. We 
already know the conclusion: Python is not mathematically pure. That 
doesn't make it wrong.

In fact, I would argue the opposite: by knowing when to bend, or break, 
mathematical purity in favour of more accessible idioms, Python is a 
better language for the majority of people.

I didn't say it was a *pure* functional language, or a *good* one.

Attacking the man, instead of the argument. Is that the best you've got? 
If you're going to cast aspersions on my character, do it properly: I'm 
an arrogant, ignorant boob who dares to questions the Great Ones who 
clearly are infallible and cannot make a mistake.
