Note that even Delphi doesn't have them yet ("it might also turn
up in Delphi in the future").
Looks as something related to:
http://en.wikipedia.org/wiki/Anonymous_function#Delphi ? If so then
this is already implemented in delphi.
From my understanding, Delphi's so-called "Anonymous Functions" work
as closures - the inner function/procedure having access to the
variables of the outer function/procedure even if the outer function
has completed execution. Delphi's anonymous functions can have names
so they don't seem to be so anonymous. Anonymous functions were
implemented in Delphi 2009.
Apparently, they are referred to as anonymous functions as the term
closures is used for something different in C++ Builder.
I still don't get what's the real use of such constructs? I see only
that it seems to encourage a hacky scripting language like coding style?
Or like Javascript. That one gives me a headache when just looking at it :(
I don't understand what is so bad about having to name a function ?
OK, in C or languages where you have only 1 namespace this may require
some thinking.
But pascal has 'local' functions, so they don't pollute your namespace.
If coded in an object, it's just a private method if you want.
And if not that, you can code it in the implementation part of
your unit. Plenty of possibilities, and you always have readable code.
