My point was not so much about def in particular, or any single change.
Rather, one's personal or even collective development should not lead to
making the language gradually more difficult to beginners IMO.

Asserting that the keyword "def" would confuse beginners is a red herring.
Scheme is AFAIK the only language whose variable binding form is _not_ some
kind of an abbreviation. C#/JavaScript use "var". Heck, D and C++11 use
"auto", which is truly bizzare. "def" is a very common keyword to use for

I can't say I like the idea for usability and compatibility reasons.
Usability:
- Try this idea exaggerated: def lmbd cwcc cdr cond tgt gg param ...
Maybe for hard core pros, but this doesn't make the language
very approachable for the beginners. I made a few new ones so

So no, it does not allow you to enter arbitrary computations. I'm not
saying that this should replace the current language-based approach, but I
think that having this for all pre-defined actions (like new tab, run,
complete, etc.) would make customizing (as apposed to augmenting) much more

On the topic of key bindings, is there a reason this can't be done in the

Hi,
Been learning Python and the docstring feature is nice, you just a
binding for it's doc and you have it in the repl and it saves you some

Thinking about Racket it seems like it would be nice. Yea I know I can

The other answers covered plotting, but for picts from the
slideshow library (for example, those returned by plot/pict), you
can use (show-pict some-pict) from slideshow/pict, which will
display that pict in a new frame.

For plot, you can use the plot-frame function:
