title: Input list to a pure function
body: <p>The syntax for a pure function is something like <code>(1+#1+#2)&amp;[a,b]</code>, which gives <code>1+a+b</code>. Now I want to supply the output from some function which looks like <code>{a,b}</code> to the function above, i.e., something like <code>(1+#1+#2)&amp;{a,b}</code>, but with the correct syntax, as that obviously doesn't work. How do I go about doing this?</p>
