+    Fix compilation with Boost 1.58
+    
+    1.58 introduces strict type checking in boost::get() and while that's
+    good in theory, the VariantUtils code makes it impractical to use.
+    Instead, use relaxed_get() to get the old behavior. relaxed_get() didn't
+    exist in older versions of Boost, so the code must check BOOST_VERSION.
+    
+    Fixes #93.
