"Debugging is twice as hard as writing the code in the first place.
Therefore, if you write the code as cleverly as possible, you are,
by definition, not smart enough to debug it." -- Brian Kernighan

I wanted to bring your attention to a number of items tied<br>
into PDL3 development/plans (at least mine) that could be<br>
of interest to you and might be an opportunity for some<br>
synergy with Prima.<br>
<br>
* David has been working on TinyCC based JIT compiling<br>
  with his C::Blocks development.  This would allow for<br>
  runtime compilation of PDL+C code.<br>
<br>
* My current thoughts for the PDL3 kernel is that it would<br>
  be lightweight, support modern perl OO similar to Moose<br>
  and perl5-mop ideas, *and* be symmetrically usable from<br>
  C and from Perl (this is where the JIT really helps!).<br>
<br>
* I think it is important that the PDL3 kernel be C-based<br>
  for portability and compatibility across platforms, libraries,<br>
  compilers...  With C++ you lose that.<br>
<br>
* Going with C I&#39;ve come across a number of techniques<br>
  for implementation:<br>

    code generator from a specification language)<br>

    compiler based on the Gnome Object system)<br>
<br>
    Prima (I finally was able to work through the internals<br>
    API and saw that it is very similar to the above and it<br>
    support symmetrically access to methods from either<br>
    C or perl layers)<br>
