Perhaps mistercow means things like def foo(): x = 5 def bar(): print x def baz(): x = 6 print x bar() baz() print x Which prints 5, 6, 5. If baz tried to print x before assigning,…

Not really -- "any" and "filter" are total functions, but "first" of an empty list is undefined. On the other hand, that also applies to foldl1 and {max,min}imum{,By}, so it's prob…

The difference is that the whole point of the Y combinator is that it's a fixed-point combinator that doesn't use explicit recursion. Imagine that you didn't have "var", and couldn…

Some methods: 1. Change your layout from "USA" to "USA International (AltGr dead keys)". Then use right-alt+key to make various special characters (you can look at what each charac…
