Needs description.

The following functions are exported for convenience in writing the grammar productions.

$node = New($name,$content,%attributes);

Creates a new XMTok node with given $name (a string or undef), and $content (a string or undef) (but at least one of name or content should be provided), and attributes.

$node = Arg($node,$n);

Returns the $n-th argument of an XMApp node; 0 is the operator node.

Annotate($node,%attributes);

Add attributes to $node.

$node = Apply($op,@args);

Create a new XMApp node representing the application of the node $op to the nodes @args.

$node = ApplyDelimited($op,@stuff);

Create a new XMApp node representing the application of the node $op to the arguments found in @stuff. @stuff are delimited arguments in the sense that the leading and trailing nodes should represent open and close delimiters and the arguments are separated by punctuation nodes.

$node = InterpretDelimited($op,@stuff);

Similar to ApplyDelimited, this interprets sequence of delimited, punctuated items as being the application of $op to those items.

$node = recApply(@ops,$arg);

Given a sequence of operators and an argument, forms the nested application op(op(...(arg)))>.

$node = InvisibleTimes;

Creates an invisible times operator.

$boole = isMatchingClose($open,$close);

Checks whether $open and $close form a ‘normal’ pair of delimiters, or if either is ”.”.

$node = Fence(@stuff);

Given a delimited sequence of nodes, starting and ending with open/close delimiters, and with intermediate nodes separated by punctuation or such, attempt to guess what type of thing is represented such as a set, absolute value, interval, and so on.

This would be a good candidate for customization!

$node = NewFormulae(@stuff);

Given a set of formulas, construct a Formulae application, if there are more than one, else just return the first.

$node = NewList(@stuff);

Given a set of expressions, construct a list application, if there are more than one, else just return the first.

$node = LeftRec($arg1,@more);

Given an expr followed by repeated (op expr), compose the left recursive tree. For example a + b + c - d would give (- (+ a b c) d)>

MaybeFunction($token);

Note the possible use of $token as a function, which may cause incorrect parsing. This is used to generate warning messages.
