Arrays
^^^^^^
Array types are also supported. They can be made of bytes, words or floats, strings, and other arrays
(although the usefulness of the latter is very limited for now)::
Array types are also supported. They can be formed from a list of bytes, words, floats, or addresses of other variables
(such as explicit address-of expressions, strings, or other array variables) - values in an array literal
always have to be constants. Putting variables inside an array has to be done on a value-by-value basis.
Here are some examples of arrays::
byte[10] array ; array of 10 bytes, initially set to 0
byte[] array = [1, 2, 3, 4] ; initialize the array, size taken from value

For next release
^^^^^^^^^^^^^^^^
- make 'intermediate' module containing the SymbolTable and dumbed down version of the Ast.
- make an intermediate representation containing the SymbolTable and dumbed down version of the Ast.
no vardecls in it anymore (these are part of the symboltable) and baked types, so no inferType too.
no name lookup in the Ast, always do this in the symbol table.
- codegen makeInitialArray()/makeArrayFillDataUnsigned():
initial array literals with address-of, or just variable references, are no longer possible at this time!!
