Yeah, I saw this when I was studying the GCC code. Sad to say I actually
understand their parser and object model now. :)
Looking at the code, they are just about to implement a new type inference
system as well, in the EXTERNC compiler I am writing, the evaluate() method
will soon take a ITypeRegistry which is the new type inference.
I know two years ago in my ignorance, I poo pooed the compiler but now that
I actually understand the source, it really is one of the best Javascript
compilers around and whether people agree with how it does advanced
optimizations, the parser itself is rock solid and totally being maintained
and advanced.
If this whole AS > JS thing takes off, it would also be worth changing all
the JSDocEMitter stuff to use their JSDocInfoBuilder class, it is a builder
that knows the exact jsdoc language for it's compiler and would make the
code 100% more flexible.
So Erik, are you saying that since it soon will fully support ES6, the
FalconJX compiler should be able to emit ES6?
