[Haskell-cafe] Lambda and closures in PHP -- could someone please comment?

[Richard A. O'Keefe]

I believe C# already has lambdas, and Java is supposed to be getting
them.  PHP is playing catchup, is all.  (Oh, and Eiffel has 'agents',
and I think I saw something about C++ Next Degeneration, and ...)
Heck, the idea has only been around in computing since the 1950s...
