Well, Python was chosen over Ruby for MIT's rework of their intro to
cs course because Python is multi-paradigm, whereas Ruby claims
everything is an object.
How would you code this simple list compression problem in Ruby:
1.08 (**) Eliminate consecutive duplicates of list elements.
If a list contains repeated elements they should be replaced with
a single copy of the element. The order of the elements should not be
changed.
Example:
?- compress([a,a,a,a,b,c,c,a,a,d,e,e,e,e],X).
X = [a,b,c,a,d,e]

yeah I guess the LOOP macro is where I got stuck in doing Lisp.

I've done Perl at corporate level for 10 years and I've heard seasoned
Perl developers say the same thing.

yeah, wxPython is the only thing for any scripting languages that
seemed to make very professional desktop UI programs.

yeah sinatra.rb looks nice for web dev and ruby on rails was a runaway
hit for awhile.
By the way, here's the Prolog solution to the compression problem I
posted earlier:
% http://sites.google.com/site/prologsite/prolog-problems/1
% Problem 1.08 - compress consecutive duplicates into a single
% list element
compress([], []).
compress([X,Y], [X,Y]) :- X \= Y.
compress([X,Y], [X]) :- X = Y.
% problems writing other clauses (thanks RLa)
compress([X,Y|Z], [X|Z1]) :- X \= Y, compress([Y|Z], Z1).
compress([X,Y|Z], Z1) :- X = Y, compress([Y|Z], Z1).
