I have a section in my prompt only shows if psvar[9] contains some string:
{5935|20:34:22|~}% psvar[9]=hello
{5936|20:34:22|~}(hello)%
but with the nameref i can do this:
{5937|20:34:47|~}% .prompt.currenttask=hi\ there
{5938|20:34:47|~}(hi there)%
which is easier (with tabcompletion). It also makes the code that sets
.prompt.gitbranch a bit clearer.
