Re: odd recursion

Thanks very much to everyone who answered.

Just to clarify -- I know the simplest solution is just to avoid it, the next most simple solution is to use
zsh/ksh function syntax rather than posix syntax.

The main point of the question was that I don't see how/why it is a recursion, from the logic of the expressions, which is why I said there was some sort of fundamental gap in my understanding of how zsh works.

The interesting thing is that if I issue

"which lf" it tells me that lf is aliased, not that it is defined as a function. If I then issue the newly defined lf command, the function takes precedence over the alias (which is what I understood to be the expected behavior), which I can see from the error messages produced.

The problem arose because a user made the alias without checking to see that the function was defined, and that the function was written as a posix function and defined after the alias in the sequence of shell initialization.

If the alias is defined after the posix function is defined, the problem doesn't arise.

I don't see any way around this, without taking away good and necessary behavior.

You can always use the really simple solution, which is not to have a name clash at all. I use a short script I wrote to tell me whether a name is already defined somewhere. It's got a bug in it w.r.t. functions (which makes it useless at the moment) but I'll (presumably) fix that.

IMHO, it is always better to keep things explicit rather than relying on the sequence of operations in the implementation.

A warning, as someone suggested, might be a better solution.
