Let's generate autocompletions for aliased subcommands.
$ source before.zsh
$ clap-test [TAB] <- gives me "foo bar --"
$ clap-test foo [TAB] <- gives me "--my-flag"
$ clap-test bar [TAB] <- no reaction
$ source after.zsh
$ clap-test [TAB] <- gives me "foo bar --"
$ clap-test foo [TAB] <- gives me "--my-flag"
$ clap-test bar [TAB] <- gives me "--my-flag"
