<a name="line-16"></a>Example use:
<a name="line-17"></a>
<a name="line-18"></a>Suppose we have a circuit:
<a name="line-19"></a>
<a name="line-20"></a> f :: (Signal Bool, Signal Bool) -> Signal Bool
<a name="line-21"></a> f (x,y) = and2 (y,x)
<a name="line-22"></a>
<a name="line-23"></a>Then we can look at its internal structure as follows:
<a name="line-24"></a>
<a name="line-25"></a> table (struct (f (var "i")))
<a name="line-26"></a>
<a name="line-27"></a>will evaluate to
<a name="line-28"></a>
<a name="line-29"></a> ([(1,And 2 3),(3,Var "i_1"),(2,Var "i_2")],Object 1)
<a name="line-30"></a>
<a name="line-31"></a>For circuits taking more complicated structures as arguments
<a name="line-32"></a>(such as lists), one has to instantiate the list size first
<a name="line-33"></a>of course.
<a name="line-34"></a>
<a name="line-35"></a>If you do not like the "Object 1" output, you can just use
<a name="line-36"></a>the function `flatten' to get a list of identifiers.
