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
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.
