#### Search: #### Eval

-- Special symbol: eval As an argument in a call to `ev (<expr>)`, `eval` causes an extra evaluation of <expr>. See `ev`.

Example: ```          (%i1) [a:b,b:c,c:d,d:e];
(%o1)                            [b, c, d, e]
(%i2) a;
(%o2)                                  b
(%i3) ev(a);
(%o3)                                  c
(%i4) ev(a),eval;
(%o4)                                  e
(%i5) a,eval,eval;
(%o5)                                  e```

There are also some inexact matches for `eval`. Try `?? eval` to see them.

```(%o1)                                true
(%i2) ```
