add multiple-assert back
and while there fix a shift-reduce conflict on '\n' in const rule
add multiline consts
now it's possible to do also things like const ( one = 1 two = 2 ... ) instead of const one = 1 const two = 2 ...
rework args and blocks: use a real stack
this solves the limitations and bugs of the previous attempt at using a single global variable. The new code is also easier to read IMHO.
