sounds complicated. why do you need to define a function for each new
directory? the prompt trick is sneaky. it relies on the space. why not
just move the space and make the thing that required a new function
an argument to a fixed function?

fn $sysname: {
}
fn cd{
builtin cd $*
awd
prompt=($sysname:' '`{basename `{pwd}}^'; ' '')
}

or you can go minimilst bourne and have

fn : {
}
fn cd{
bultin cd $*
awd
prompt=(': '`{basename `{pwd}}^'; ' '')
}
