Hello,
In the past I wrote about pascal's ; mistake.
; should be used as a continuator.
I just made a programming mistake which solidifies/merits my idea:
The programming mistake was this:
vBattlefieldLosingWarrior :=
// modified warrior and brain
vSimulatorWinningWarrior := vBattlefieldBattle.Warrior[0];
Code should look like this:
vBattlefieldLosingWarrior :=
TBattlefieldWarrior(vBattlefieldBattle.Warrior[2].Association);
// modified warrior and brain
vSimulatorWinningWarrior := vBattlefieldBattle.Warrior[0];
Fortunately there was a type mistmatch which hinted me at the programming
mistake.
The code is a bit messy above so let's make a simpler example to understand,
the in my oppinion, dangerous programming mistake:
A :=
B := C;
The above statements "A :=" is valid in Delphi's current design.
The danger is that B is assigned to A which is not what I wanted, the
problem was missing code at A.
So the danger is that some day, somebody will write B in such a way that it
will accidently be assigned to A.
By using ";" as a continuator instead of a "seperator" the code would look
as follows:
A :=
B := C
Since there was no continuator specified, "future-Delphi" would have been
able to detect this programming mistake.
Since it won't try to attach B to A since there is no continuator symbol.
I found it worth it to mention this so there ya go.
I am always glad when Delphi finds bugs like these... fortunately this time
I got lucky thanks to a type mismatch.
Also the statement would have looked like A:=B:=C; which I think is not a
valid statement in Delphi.
I ll test that just to be sure.
Yes fortunately Delphi does not allow such dangerous statements.
However I think C does, I am pretty sure of it. Another nice example why C
is dangerous ! ;)
(Also my request for python is the ":" symbol removed from language and
instead require statements to be on next line below if statement that be
nice)
(Currently the ":" is perceived by me as unnecessary and annoying, an easy
typo to make just like forgetting a ";" however these are not necessary in
python so why remove ";" but not ":" ? seems inconsistent, and ya know me...
I don't like inconsistencies, it's frikking annoying.).
Bye,
Skybuck.
