Good points, all. I think I misliked Pascal's nested procedures because they weren't true lambdas; once the outer procedure returned, the inner procs were no longer callable (just one contiguous stack, right?). Early-on, using C++ lambdas, I found myself making the same mistake in a design for some asynchronous completion stuff. Embarrassing; C++ and Pascal are not JavaScript/Lisp/Scheme/Smalltalk :-)

You can assign a c++ lambda into an object for later use, you just have to be careful about capture by reference and capturing pointer types... But the capture using the copy constructor is handy here, eg. you can copy a shared_ptr and get reference counted captures... It's funny in this way how c++ lambdas lead to very c++ specific issues and uniquely c++-ish solutions. I think the wackiness of the closure capture mechanism is the best example of this I can think of.

Misliked?

    Not sure what your point is, but it's a real word :-)
