I'm always torn on this sort of issue. While I'm a fan of simple/regular/
orthogonal behaviour, I also believe there's an argument for stopping before
the language disappears entirely.
The main thing I have against Ruby is that they use anonymous function
blocks all over the place. It's regular - and being a functional programmer
at heart, it's quite cool - but I think the language is less readable
because of it. I mean (taking an example from the "Programming Ruby" online
[ 'cat', 'dog', 'horse' ].each do |animal|
print animal, " -- "
This is a great idea, but something went wrong along the way. The language
became so simple as to be almost meaningless, with all of the actual meaning
becoming particular idioms.
The problem with this is that different programmers have different idioms
and the code becomes less portable (between minds rather than platforms).
As a language designer, or BDFL, there's a fine line to walk between keeping
the language growing and expressive, keeping it simple and regular, and just
keeping it sensible. Guido's done a pretty good job in my opinion. I'd say
that Python is my "Goldilocks" language - not too restrictive, not too
