Simple Meta Object Programming / Simple Matter Of Programming

is a C based interpreter (runloop) that executes, what different compiler (like Mildew ) produce.

If you want to help SMOP, you can just take on one of the lowlevel S1P implementations and write it. If you have any questions ask ruoso or pmurias at #perl6 @

The Slides for the talk Perl 6 is just a SMOP are available, it introduces a bit of the reasoning behind SMOP. A newer version of the talk presented at YAPC::EU 2008 is available

SMOP is an alternative implementation of a C engine to run Perl 6. It is focused in getting the most pragmatic approach possible, but still focusing in being able to support all Perl 6 features. Its core resembles Perl 5 in some ways, and it differs from Parrot in many ways, including the fact that SMOP is not a Virtual Machine. SMOP is simply a runtime engine that happens to have a interpreter run loop.

The main difference between SMOP and Parrot (besides the not-being-a-vm thing), is that SMOP is from bottom-up an implementation of the Perl 6 OO features, in a way that SMOP should be able to do a full bootstrap of the Perl 6 type system. Parrot on the other hand have a much more static low-level implementation (the PMC)

The same way PGE is a project on top of Parrot, SMOP will need a grammar engine for itself.
SMOP is the implementation that is stressing the meta object protocol more than any other implementation, and so far that has been a very fruitful exercise, with Larry making many clarifications on the object system thanks to SMOP.
