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.
