Try:
f[x___]:={x}
f[a,b] gives {a,b}

Objet: [mg11801] Questions about functions.
I will appreciate your input to these two questions.
1 - How can I convert the sequence of all arguments of a function into
a list ? In vain I tried f[x__] := List @@ x
2 - How can I make functions which use their own names , for instance so
that s[e,f] for some symbol s and all expressions e , f
becomes (s+e)(s+f) ?
Many thanks
