Notes
Composed of Notes
The <Expression> components of a
<Function> instance, if any, represent
the arguments of the function being represented, so a
<Function> instance has
<Expression> components if that
<Function> instance takes arguments. The
<Expression> components
are ordered so as to unambiguously specify which
<Expression> component
is being supplied for each argument of the
<Function> instance.
The exact interpretation of each argument is defined by
the specific function.
Fields Notes
The value_type of a
<Function> instance specifies the
type of value returned.
The function field specifies the
function to be used to determine the value of the expression
when it is evaluated.
