8f2e9c6b94 FIXED: char_type/2 for unbound first argument. 
Surrogate pairs form a gap in valid character codes, see:

98a046500f MODIFIED: (->)/2 in DCGs is now only supported in the context of if-then-else. 
That is, ( If -> Then ; Else ) is still supported, but ( If -> Then ) not.

The only solutions for `Z #= X^Z` are `X = Z, X in -1\/1`. Also helps
avoid big numbers.

e702fe5c68 ADDED: Support for higher-order non-terminals phrase//[2,3] 
These non-terminals take a grammar rule body and additional arguments
as arguments. These arguments are appended to the first argument.

A key motivation for the introduction of these non-terminals is found
in the discussion and sample code provided by @bakaq in:

    https://github.com/mthom/scryer-prolog/discussions/2260

In this way, portable higher-order DCG programming is possible while
keeping the logical grammar rule expansion implementation dependent.

Example:

    ?- phrase(phrase('.', a, []), Cs).
       Cs = "a".
