    base: MRP-refactoring of AMP instances
    
    Summary:
    This refactors (>>)/(*>)/return/pure methods into normalform.
    
    The redundant explicit `return` method definitions are dropped
    altogether.
    
    This results in measurable runtime improvements in nofib of up
    to -20% runtime (geometric mean: -7%) in my measurements.
