Python also uses "&" for set intersection afaik.
Yes, but that's an overload of the&-Operator and it makes sense.
We should add "and" and "or" this makes the Code way more readable, imo.
But I spent years learning&& and ||, when I read code, these patterns
jump out at me. Sure they aren't as "readable" but we're writing a
program here, not the Illiad. I write in a programming language, not
english, if I wanted to write in english, I'd go be an author, or a
journalist.
As people have mentioned, it only makes the code more readable (and
even that is under debate) for english-speaking users, foreign
language users are at even more of a disadvantage, since the have an
extra step of analysis to figure out what it means, especially since
there might not always be a simple translation.
Don't think of&& and || as `and` and `or`, think of them more as
logical conjuction and disjunction, they are predicate operators.
And if we want to get into "proper" symbols for logic, we should be
using ∧, ∨, ⊕, ¬ for and, or, exclusive or and not, since those are
the proper boolean algebra symbols.

Then use Haskell :P. http://www.haskell.org/haskellwiki/Unicode-symbols
Everyone who codes in the "D programming language" knows english, since
the whole internetz is english, like the D documentation, so it
shouldn't be a problem to get the meaning of "and" and "or".
