There are currently a lot of PMC types implemented directly in Parrot.
If you look in the classes/ subdirectory of the Parrot distribution you
see lots of files named "perlint.pmc" and so forth. These are the
builtin PMC types...
The fun about dynamically loadable PMC types is that if a language L
needs/wants its own interesting implementation of a datatype T so that
the L compiler writers can generate PIR like:
P1=new LT
then there is no need to extend the core Parrot engine (and clutter all
non-L users with the necessity to carry the LT implementation around).
Instead, one could do
load_ext "LT" # or whatever
P1=new LT
to dynamically load the implementation of the LT data type from a shared
library (or DLL, or LPA load module, or whatever your operating system
groks).
