It's simply a syntactic marker specific to "for" which looks for it in
the list of arguments.  In the original shell syntax it's not
really doing much except make it a bit more readable since you're forced
to use "for var in ...", but zsh makes a virtue of it by allowing you
to do "for var1 var2... in ..." --- unless your variable is called "in",
obviously, in which case you can't.
