    LESS, ADD ...
 - +=, -=, ...
 - constanter
 - initializers
 - infinet loops
 - default initalization

 - vectorer
    - (1, 2) + (3, 4) = (4, 6)
 - bättre rust functions länkning
 - listor
 - set
 - escape newline
 - variable not found in outer scope - SHould crash not infinet loop
 - Show stack values affected
 - Debugmode -- ensure stack semantics (like pop2)
 - else -- syntax highlight
 - automatic epsilon on floats
