Is there a way to make global aliases more available?

Is there a way to make global aliases more available?

Hi
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?

No, aliases are by design very limited things that get replaced on input
before any parsing is done.

It would be far simpler to use a variable; the following seems to work.

EMPTYSTR='[[:space:][:INCOMPLETE:][:INVALID:]$'\e']#'
[[ " " = (#b)(${~EMPTYSTR}) ]]

Which is a feature, not a bug.  Sometimes you want things to behave 
stupidly.  One of my own favorite programs is a mouse cursor hopper -- 
good when you have multiple screens and multiple terminals,  I hit the 
hotkey and the cursor jumps to a set open terminal.  And it's absolutely 
stupid, it does not do any 'helpful' things like worry about what's 
visible on the monitor it just jumps.   Nothing to think about or worry 
about.  Dumb is good.
