What do you think about the set-car! thing? Why not just use Erlang instead?

Can you elaborate?

Maybe I misunderstood, but it seems to me that without set-car!, Scheme becomes more like Erlang in respect to "unchangeable variables" (don't remember the proper term right now).

I had recently evaluated Erlang but found some things very difficult to achieve. For a contrieved problem, how do you program an effective algorithm to calculate prime numbers in Erlang?

So I felt quite good about the destructive operators of Scheme. If they are now wanted anymore, I might reconsider using Erlang.

Stumbled upon this while checking out the blog:

Very impressive. The features in Dr. Scheme make for an excellent teaching environment, but look like they would work well for a working programmer, also.

I have no experience with lisp or scheme, but reading the new tutorial on their website was such a beautiful introduction to programming, and then I looked at the source code for the tutorial and was blown away at the level of simplicity and sophistication they have achieved.

So why have I never heard of PLT Scheme? Why isn't it popular?

I think it's probably the premiere Scheme implementation. Arc is built in it (you may have heard only of MzScheme, but that's in the PLT family). I happen to be using it for my startup.

As far as various Schemes go, I'd say it's very popular.

Wow, they made the site much cleaner as well.
