Creates table for fixity declarations to build expression parser using pre-build and user-defined operator/fixity declarations

Calculates table for fixity declarations

Binary operator

Prefix operator

Backtick operator

Operator without fixity (throws an error)

Parses an operator in function position i.e. enclosed by `()', with an optional namespace

  OperatorFront ::=
    '(' '=' ')'
    | (Identifier_t .)? '(' Operator_t ')'
    ;

Parses a function (either normal name or operator)

  FnName ::= Name | OperatorFront;

Parses a fixity declaration Fixity ::= FixityType Natural_t OperatorList Terminator ;

Check that a declaration of an operator also has fixity declared

Checks that an operator name also has a fixity declaration

Parses a fixity declaration type (i.e. infix or prefix, associtavity) FixityType ::= 'infixl' | 'infixr' | 'infix' | prefix ;
