title: Dealing with subscripted variables
body: <p>Suppose I define the following (bad) pattern</p>
  
  <pre><code>Subscript[\[Beta], i_][x_] := Subscript[\[Beta], i][x[[i]]];
  </code></pre>
  
  <ol>
  <li><p>Is it possible to clear this pattern without clearing definitions for all the other subscripted variables? My first thought would be to modify Subscript's DownValues, but it seems to be empty</p></li>
  <li><p>Is it possible/practical to have functions with subscripted arguments? IE, something along the lines of <code>f[x_1,x_2,x_3]:=Total[x_#&amp;/@Range[3]]</code>. I've heard people use <code>Symbolize</code> to help with subscripts, would it work here?</p></li>
  </ol>
