[Mono-dev] Trivial Enumerable Optimizations

[Jb Evain]

Hey,

Sorry, I reviewed this patch on IRC, and should have done it here.

My point was that basically, there's no any way to make sure that
Count will throw if the collection has more than int.MaxValue items.
So the only optimizable code path is if the source is an array, which
is already done.

To me the only way is to enumerate over the elements to get the
LongLength, and Robert's test case shows that .net does the same.

So this patch is not making it in.
