One of the reasons I dislike boost is in the first code sample. What’s the point of implementing what boils down to a 10 line function (as shown in the decompiled output) like this
```
    typedef xor_combine_engine&lt;
  xor_combine_engine&lt;
    linear_feedback_shift_engine&lt;uint32_t, 32, 31, 13, 12&gt;, 0,
    linear_feedback_shift_engine&lt;uint32_t, 32, 29, 2, 4&gt;, 0&gt;, 0,
  linear_feedback_shift_engine&lt;uint32_t, 32, 28, 3, 17&gt;, 0&gt; taus88;
```

  I completely agree. Every time I remove boost from projects the build times drop dramatically and it usually doesn't take much work to swap the boost code for something else that isn't template fetish art.
