I define a global alias:

alias -g EMPTYSTR='[[:space:][:INCOMPLETE:][:INVALID:]$'\e']#'

to then use it in [[ "" == EMPTYSTR ]]. It works, however any addition to the alias name makes it inactive, e.g.:

[[ "" == (EMPTYSTR) ]]

[[ "" == (#b)(EMPTYSTR) ]]

won't work. Is there any way to somehow improve the alias recognizability?

Best regards,
