The following is a list of the tokens used by YASS and their byte-code representations. These values are used by the compiler when it constructs the IAST. Some entries represent internal compiler nodes rather than source-code keywords, so their keyword column is blank.

DOUBLE_ARROW is an alias of ASSOCIATION, and
UNION_TYPE is an alias of PIPE. Each pair therefore
shares a byte-code value.
SPECIAL_KEYWORD is assigned to context-sensitive words that do
not need separate byte-code values. The current special keywords are
increase, by, and online.
