I've used Smalltalk and I've been making a living programming in Ruby
for the last 18 months. Now that you point that out, it is one of the
large advantages that Ruby has over Smalltalk w.r.t
experimentation / prototyping / learning curve

Is Erlang tied to Prolog in this? If not, why does that matter?

I've found the transparency between the interactive shell and source
environments in Ruby to be nothing but a huge boost in productivity.
I've never had this "shooting myself in the foot" effect because of it.
If there is something intrinsically different about the Erlang world that
makes it dangerous, I would appreciate it if you could elaborate.
