Could you define modern? Nearly all "modern" languages seem to leverage early seventies C syntax, except Python of course, which, as Florian already adeptly remarked is more a sixties syntax. > My main gripes with Delphi/pascal is its additional verbosity and Ah, verbosity is one of the things I actually like about it. > somewhat tedious coding practices which seem superfluous in some cases. .... because it saves bugs, and costly debugging. > Now I dont mind typing a bit extra to make code cleaner and more legible > but I have a few ideas which would reduce needless typing and improve > clarity at the same time. > > (feel free to shoot down any of these ideas) > > 1.

They are not really auto managed, nor refcounted. They simply exist for the near entire life of the program (except startup and shutdown), or are manually created. > The best solution I can > think for this is to reference count non-component classes.

This is impossible. 90% of the language wouldn't work anymore as it does now, and besides, it would be dog slow. Could be that it gets slower than Boehm GC even. > This will improve legibility of code too as there will no longer be a need > for having loads of try..finally statements to free stuff. How do you free objects then? Those try..finally's are there actually because of the refcounting. > 2. For Each. Its in Delphi 2005 and every modern language implements it.

However the solution is to make a lib with better types. Pulling it in the compiler with ref counting however is something totally else, and will make them dog slow. Keep in mind that I can walk through 5-6 million (real world) objects in just under 2 secs in Pascal/Delphi on an already old 2GHz P IV, and inspect them all. Try that in Python. _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
