I just noticed that there is an operator '=:'. What is it used for? 

At the moment I have disabled ':' a_expr in the parser since it's not
distinguishable from a variable. The same problem appears with this
operator. But it can be worked around by using '= :<var>' instead of
'=:<var>'. On the other hand I wonder whether this operator is still needed
when ':' is not allowed in a_expr, b_expr, ...
