Yes and no, respectively.  In other words, nothing new here.

Strings can be made immutable (in both Llama and OCaml) by disabling
String.set in the standard library (the s.[i] <- c construct is just sugar
for a call to that function).

Is there a better approach to polymorphic equality floating around?
