I beg to differ.
Recently I rewrote a python program (on linux). The pascal version was
shorter and much clearer to understand. The python syntax is a horror
as far as I'm concerned.
What makes python interesting are the many classes it offers by default
to perform standard tasks, especially in the text treatment department;
regular expression stuff etc.
The same goes for most languages; Mostly it's not the language syntax
that determines the productivity factor; it's the number of standard
Quabbling about being able to type
is beside the question. If your productivity depends on that, you're
either in the wrong business, or you are using the wrong kind of editor.
A good IDE/Editor has tools to make typing less cumbersome.
In the company where I work, 4 languages are in use: Delphi, VB, C++
and PHP. In order of descreasing productivity they are rated as follows:
The order of VB/PHP was the most surprising for me; but that can maybe
be explained by the kind of app the language is used for.
Pascal is a language that allows you to develop in many styles, with as
much or as little optimization as you want, and all along it keeps your
code readable, which is very important when you work in team and you
need to read other people's code frequently. To see what I mean, try
reading this little 'gem':
(better yet, run it)
