I can't do it in Perl. I can't even quantify the amount of money we've
already lost by using Perl. By not supporting OO, I mean things like the
fact that if you define a member function of a class, then
$classname::functionname($arg1, $arg2);
and
$classname->functionname($arg1, $arg2);
will both compile, but one is a static function that passes the class name
as the first argument, and the other is a non-static function that passes
the arguments as listed. No one on any Perl list that I'm on could make
sense of why they did that. If you wanted a static function, you'd make it
static; otherwise, you'd make it non-static. The way Perl does it, you
have to put some logic at the beginning of your function to check whether
the first argument is the class name, and if it is, branch into the
"static" function code, or else branch to the "non-static" function
code. Bizarre. I think that to the maximum extent possible, a programming
language should ensure that a typo will cause the program *not to run*,
instead of running and doing something unexpected.
Has anyone used a beta of Visual Studio .NET enough to know if it can do
all of this? i.e. being able to do something along the lines of
user myuser = user.GetObjectFromTableRow("bennett");
myuser.sendReminders();
myuser.emailaddress = '[EMAIL PROTECTED]';
in three lines -- with Perl and MySQL it takes about 20.
I think there are some purposes that free, open-source software is better
suited for (security protocols and other well-defined problems that don't
change with a constantly changing technological environment), however the
question of when and when not to use open source software is clouded by the
notion that open-source software is always better. If I'm going to be
using an IDE to do rapid application development, I want a
**closed-source**, **proprietary** system that **costs money** :)
