var strlist : TStringlist;
strlist := Tstringlist.create;
I know strlist is a Tstringlist, the compiler knows it too as I have declared
it so why do I have to spell it out in the creation process?
For 2 reasons:
First, with
strlist.create;
It is not clear whether strlist is already initialized or not;
there is no way it can now this.
strlist := Tstringlist.create;
makes this explicitly clear.
Second, with
strlist.create;
It is not clear from reading whether create is a constructor or not.
Create() is just a convention, which you can decide to ignore.
Here again, with
strlist := TStringlist.create;
Create MUST be a constructor, since you are initializing the variable.
Look at other languages: VB, PHP, Perl, Python.
They all require the use of the 'new' (or a variant thereof) keyword
when the constructor must be called:
strlist = new tstringlist;
