a function to put environment variable in zsh history for editing

function eve (); { eval "print -s ${1?no variable}=\'\$$1\'" }
This only makes sense if you are using command line editing. Create the function in your current zsh session, then type eve PATH go 'UP' in your history and notice the current (editable) definition of PATH shows up as the previous command. Same as doing: PATH="'$PATH'" but takes fewer characters and you don't have to remember the escaping.
