 * In the code:
 {{{
 #if defined(_MSC_VER) && (_MSC_VER >= 1020)
 #pragma once      // MS compatible compilers support #pragma once
 #endif
 }}}
    why do we have to check for 1020? We do not support < than VC7.1
 anyway.

  * Is pragma really speeding up compile times? I'd love to see some
 concrete numbers. Some informal tests reveal no speed improvements. It
 seems that the bulk of the compile time is spent in instantiating the
 templates and expanding the macros anyway, no?
