The only languages that have taken this idea seriously is the Lisp
family, which have macro systems that basically allow the programmer 
to extend the language. In short: the Lisps have an extensible syntax,
where Perl just has an extensive syntax. 

Python (and Ruby, for that matter) remind me more of Smalltalk than
anything else -- ie, they have extensive libraries, a community with a
love of elegance but not of purity[*], and a greater focus on practical
applications than on academic research. 

The differences are that there's less of a closed-world attitude in
Python than in the ST world, though -- Python can be used for sysadmin
work where ST (even Squeak) wouldn't be a natural fit. But on the flip
side Smalltalk has always had a stronger focus on UI and dev
environments.  This is changing, though -- the ST culture is beginning
to value the ability to deal with the world outside the system image,
and Guido's latest enthusiasm is "computer programming for everybody"
(which is a very ST-ish sort of idea).
