Completion

compdef _func new can use func's completion for the new command. However the new cannot be an alias when complete_aliases is not set. It's because the alias will be expanded before invoking completion function and the original command will be completed instead. Use function instead of alias to make the compdef work.

Press ^X? (Ctrl+X ?) instead of Tab to run _complete_debug. This places a trace of the completion code into a file which you can view by pressing Up Enter. Alternatively, if you want to generate a trace of a specific function while you're debugging it, add this to the beginning of your function to get an execution trace:

setopt local_options xtrace

Use echo ${_comps[brew]} to check the completion function of a command.
