This I think is wrong. noglob and nocorrect should be treated
as special case and word following should be checked for
existence of alias. (not just command)

Hmm, then I think functions should be recommended instead of
alias atleast for risky commands like 'rm;

Umm, this was not a question. This was part of example.
I was just showing what happens without noglob.

As already pointed above noglob does not call rm with -i

Probably you mean nocorrect instead of noglob.

This actually was side question unrelated to this thread.

I know, I already stated that this does not cause any harm.

But what I meant that I would still prefer zsh to trigger
a warning whether I used noglob OR not.

I NEVER do 'rm *'. So if there is rm * on command line that surely 
means, its by mistake, so I would prefer to see a warning,  even if 
there is 'noglob'.

Yep, even I think I should switch to 'functions'!


But I would again propose that 'noglob' and 'nocorrect' should
not treat next word as command, it should also check for alias.

Thanks for your replies
