} Thanks. But what does the '>|' mean here, please?

Sorry, this example might be clearer:

    fc -e '() { print echo $zsh_eval_context >| $1 }'

"fc -e" constructs the editor command by appending a temporary file name
to the argument string and then "eval"-ing it.  So ending the string
with ">|" means to clobber that file (in the no_clobber option sense).
