Looking at compiler inline...

om,
I looked at how inlining works and made a few discoveries.
When you put " self inline: true." in your method it doesn't seem to
have any direct effect on the compiler. There is a rule to process that
method but it only has the effect of emitting a comment to the body of
the C function. My theory is that nearly all semantic processing is done
in the final C code generation phase and because the function of all of
the methods which generate syntactic elements can only emit symbols to
the output stream and not go back and adjust previously emitted
elements, there is no way in the current code to correctly process the
modifier "inline".
The next thing I tried was to change the prefferances of VMMaker to
disable inlining.
This caused the compiler to generate a file was broken on the unix
platform due to some ill-advised post-proccessing by "gnuify" ( sorry,
Ian...)
The compiler is definitely due for a rewrite. It should have a deeper
"understanding" of C and it's structure. Right now it generates C code
by very simple pattern templates...
