Re: Ruby aesthetics

Hi,

I am too hoping that we will have this discussion in a friendly
environment, as we are all Ruby lovers :)

I used Perl before I used Python.  The primary driving force behind the
switch from Perl to Python is the special issue of "Linux Magazine" on
Python (even until now I think the Linux Magazine editors are still Python
supporters).  They shared their experience on how wonderful the Python
code was, and I tried it.  And coming from some Perl background, it
was!  Compared to Perl, code and object model in Python are very
clean.  After programming years in free-form languages, I could really
appreciate the advantages of indentation-based syntax.

What finally turned me off was that in Python the object is modeled rather
crudely using a hash (in Ruby also, but not as naked as in Python).  For
example, to access the object instance variable, the object method is
defined as

    def f1 (self, x1, x2, ....)
        self.x1 = x1
    ....

This shows how crude the object model is in Python.  (Well, in Ruby we
don't see this until we code Ruby in C :) .)

Then when I finally switched from Python to Ruby, I felt like I switched
to "a (very much) better Perl" than to "a better Python".  In other words,
there is no question regarding comparison between Perl and Ruby; but
Python and Perl, well, let's just say that the two are different :) ...

Regarding whether Matz knew Python or not before he wrote Ruby, let's ask
Matz...

Regards,

Bill
