Hey Luc,
That's a cool casting strategy to cleanly build a standard way to get at

My strategy here would be different, the conversion fn would be part of
the cell attributes. Maybe with the help of a lightweight factory fn to ease
record allocation.
The Convertable protocol would simply refer to the closure attribute, call it
and pass this as the unique parameter.

It sounds like you have issue with working with something as low level as
deftype not with protocols nor how they are intended to be used. Most
people don't need to bother with equivalence or lookup - they have
defrecord.

The only exception is mutable fields in the type where you don't want
uncontrolled access. There you indeed need a protocol to handle the
synchronisation of the field access.

Access internal state?
Like __hash in your code.
For example, the earlier hash example cannot be put as an extension.
Why should most extensions manipulate mutable fields?
Most certainly won't. Now none of them can.

With the browser-connected REPL, the browser JS engine is used to
