Slava,
It would be nice if the default BOA-style constructors for tuples are always
available even if the user provides a custom constructor.
For example:
TUPLE: point x y z ;
C: point ... ;
So even though the user specified a custom constructor with special behaviour,

Hello,
Below is an implementation of closures with parameters. Some examples are
below.
The example transcript was made with my listener mod. So after each line of
input, you'll see the output which is laid out like this:
<<>>

Why the variables? All you really need for closures is curry, and

example of use: 1 [ [ + ] curry ] call => [ 1 + ]; 1 2 [ [ + ] curry ]
call call => 3. It's

Yeah, I noticed the listener-hook variable and I'd prefer to add things to a
hook. However...

Slava,
The help for rethrow has an example but it seems to demonstrate catch instead
of rethrow. Did you mean for that example to go in the help for catch?
