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
this purpose (Clojure, Scala, Groovy, Java, Ruby - the list goes on).
There are valid arguments against introducing the syntax - Scheme
tradition, the abundance of other forms that all include "define", avoiding
redundancy, the fact that languages in general do not have a bunch of
equivalent keywords for binding variables. But
readability/familiarity/understandability is not one of them. I would be
flabbergasted if the words {"let", "var", "val", "def", ...} were confusing
to any beginner.
