Well, I know some FP (Scheme/newLISP) but they don't have an
"any"
function. I don't know about F#, but my guess would be that it
would do
the same thing as C# would (for obvious reasons).
Are you thinking of a language in particular that has D's
behavior? Or
is this just a guess?
Ruby has any?:
http://ruby-doc.org/core-1.9.3/Enumerable.html#method-i-any-3F
And it's the best of the two worlds: given a block (a lambda)
it works like D. Give no lambda and it just returns true if the
enumerable has any elements.
Ruby wins again. :-P
This is in fact the exact behaviour of .NET's Any (on
IEnumerable). This is a library thing, not a language thing.
