parser: Split block into small functions

Since it is possible to look a future token without consuming it, it was
possible to split the block parser into small chunks of code.

There is the performance drawback, because now the parser makes multiple
lookups to the same token. However IMO that it is not a big concern
given the small computation required to get a token. Also it can be
easily addressed by computing all token in advance.

Memory Leak:

During the refactor I found some extra memory leaks related to not
released scopes. So then, more than just printing a message I introduced
an assert on scope.c to make sure developers will get this feedback asap
because our testing framework suppress messages from stderr when the
test passes.
