Fonts are used in this document to convey information.
Sometimes a glossary term appears subscripted,
as in "whitespace_2."
Such a notation selects one particular Glossary definition out of several,
in this case the second.
The subscript notation for Glossary terms is generally used where the
context might be insufficient to disambiguate among the available definitions.
Denotes the introduction of a formal term locally to the current text.
There is still a corresponding glossary entry, and is formally equivalent
to a use of "name," but the hope is that making such uses
conspicuous will save the reader a trip to the glossary in some cases.
This font is also used for certain standardized names that are not
names of external symbols of the COMMON-LISP package,
such as keywords_1,
package names,
and loop keywords.
In some situations the notation "<<name>>" (i.e., the same font, but with surrounding "angle brackets") is used instead in order to provide better visual separation from surrounding characters. These "angle brackets" are metasyntactic, and never actually appear in program input or output.
