Sorry for the confusing thread title. Ran out of space.

I need an alias to recognize either the name of the alias calling it, or the filepath of the alias calling it.

For example:
alias customA { 
   customB test-text

alias customB {
   echo -a $nameOfCallingAlias wants to say $1-

Running alias customA would result in an echo of "customA wants to say test-text"
Optionally, I could use $isalias(customA).fname to get customA's filepath. So in essence, as an alternative, I could use "$isalias($nameOfCallingAlias).fname".

What I need to know is... can I do that? Is there a non-fictional identifier to replace my mythological $nameOfCallingAlias ?
