But whas the point? you could have pre-defined 'f' anyway in your
bashrc.
not to forget, much more efficient too...gets defined only once...and
writing lines of shell code in an alias sources it....sourcing is
different from writing a script in many ways....
it moves on...

you can 'define' a function, yes. But whats your point? alias is a
literal expansion. its very much like a pre-processor operation.
alias foo="function bar() { echo hello world; }"
will only 'define' the function 'bar' when you type 'foo'. Its just
that instead of having to type of the entire function, you typed out
'foo'. and the above example is slightly misleading, in a way, in that
if people try to type 'foo test message', they would get syntax errors
because it does literal expansion.
some examples:
$ alias intemp="cd /tmp; "
$ intemp ls
<output of ls>
$ pwd
/tmp
$ alias obfuscated="function myfunc() {"
$ obfuscated echo hello world; }; myfunc
hello world
$
