This is basically what my idea behind the lambs syntax was: only one expression or statement and no variable, type or constant declarations. And for more complex use case there are either Delphi's anonymous functions or FPC's nested procedures/functions. > anonymous function, then would *always* require > a. sort( Function; prototype TMyCompare; [var ...] begin ... end ) > > the protopybe (modifier) could work for named procedures too.

Now with the named example I understand the use of the ";" after the "function"... Regards, Sven
