I've got colleagues/friends who seriously argues that in ordinary prose, we should stsart enclosing conditions in parentheses, 'If (it is raining), use an umbrella'. It would make the text clearer and less ambiguous, they claim. Seriously.
I counter by pointing out that Pascal didn't require parentheses, yet there was no ambiguiety. But then you have to use a 'then'! my friends argue. To prove their point they dig up a dozen quotes from different prose texts, where recognized authors write sentences of the kind 'If it is raining, use an umbrella'. Which proves that the 'then' is superfluous. Pascal was wrong! Parentheses are far more general that this silly 'then', e.g. you can use the same mechanism for grouping partial conditions as you use for delimiting the full condition.
I am serious: They are serious, insisting on introducing C syntax in prose.
In my younger days, I found it fascinating trying to work out counterarguments to such logic. Now I am so old that I just shake my head in disbelief.
