I find it odd that you would be on a list for es, if you don't use it.
Whatever... :-)

This solution is static.  That is to say that the prompt will not
change when the currect directory changes.

I suggest something based on one of the following:

let (o = $fn-%prompt) { fn %prompt {prompt = `{pwd}^' '; $o}}
let (o = $fn-cd) { fn cd {$o $*; prompt = `{pwd}^' '}}

The first solution will rerun the binding to prompt before each
display at the expense of a minor amount of extra delay.  The second
solution will only rerun the binding after 'cd' changes it.  The
problem with the second approach is that it will not work in any case
where es program fragments have a let binding to the original 'cd'.

>Anyway, I agree with you that es is quite nice!

I sometimes wonder why more people don't use it.
