While technically true, that doesn't enter into the issue. At the time a word is read, the parser can't tell whether or not it introduces a simple command or function definition. Posix, for instance, explicitly notes that alias expansion is performed before examining any grammar rules, and certainly without performing any lookahead. I probably cribbed the "simple command" language from Posix, which doesn't allow reserved words, which introduce compound commands, to be aliased.
