I think the dynamic alias name feature could be handy. I'd vote for it.

Maybe something like:

alias -w test* echo -a This is $aliasname

/testthis => This is this
/testbanana => This is banana


On a side note, you shouldn't include unrelated reasoning/requests in your feature suggestions/posts. Clearly, it causes unnecessary arguments that could have made a perfectly valid suggestion be dismissed as useless, etc.
