There is no goto loop in the code, only a goto jump at the end of the alias, to avoid writing the /echo string twice.
It would be worthwhile to add then, heck, we've got /ulist don't we?
Maybe. I didn't comment on the usefulness of a built-in /hlist, if that's what you thought. The scripted /hlist was a reply to neophyte's first post where he said
"I know one could use if $hget(name) to find out if a table exists or not, but it isn't exactly suited for mass searching/listing."
